d4 kills 1. Nc6
How???
what will black play
2. d5 although 2. e5 is also playable
nc3
come on mate this 3.nc3 idea as a refutation has been outdated for at least a decade.
it is now well known that 1.e4 nc6 2.d4 d5 3.nc3 dxe4 4. d5 nb8! 5.nxe4 c6 almost immediately equalizes

Bg5 with the idea of Qd4 or Qe2 and O-O-O seems decent
I'm not the biggest fan of playing as white. I also prefer playing the Reti Opening as a waiting move to see what my opponent does before playing e4 or d4. But when I play 1. e4 probably the Sicilian is my least favorite to face as my opening prep is either lacking or playing a VERY dubious form of the Alapin with Bd3 Bc2 b3 Bb2 aiming both of my bishops at a (hopefully) kingside castle.
when they beat me
sicilian
Anything open or confrontational. I don’t like to take risks (which is why I stopped playing 1.e4) but when I did play e4 my least favorite opening to play against was just 1…e5.
I don't like taking risks either but I recently changed to 1 e4 because of the book Keep It Simple 1 e4. It seems to me the repertoire helps keep risks down. For instance, you mention 1...e5. Against that the author Christof Sielecki uses 2 Nf3 and then after 2...Nc6 plays the other knight out 3 Nc3. After 2...Nf6 3 Nc3 again. If it reaches the Four Knights he plays the 4 d4 (Scotch Four Knights) which is a fairly safe though sort of drawish opening. If In the Petroff black wants to stay within Petroff realms he can play 3...Bb4 but then white can enter a Berlin Reversed a tempo up, once against rather safe.

I don't like to take risks but I enjoy closed positions where it is more maneuvering. I am not able to easily handle open positions very well, and I prefer to keep as many pieces and pawns on the board as possible.
I do have a 1.e4 repertoire that somewhat fits my criteria, although I would never dare try it in a serious OTB game. Against 1...e5, I play the Ruy, and then exchange (no matter what) and then proceed to play the resulting structure.
some random dubous opening where you put your pawns on e6 and d6 with your knights where the pawns once were where your opponent is playing waiting moves hoping you would castle so they can attack your kingside.
Against Hippo-style openings, I've found success in playing e4 d4 c4 Nc3 f4 Nf3 Be3 Bd3 Qd2 Ke2 and just moving my entire structure towards the enemy. Since they're playing useless waiting moves, just play useful waiting moves by taking all of the free space and then taking the time to sit and think about how to best defend it. I hardly lose those games anymore, since the players who play Hippo-style usually don't actually know how to play a closed game.
"hypermodern" pawn pushing "trench weasels"
pirc- Modern Geller System (can transpose into d6 Sicilian, Philidor, or Declined Nimzowitsch), or Harmonist (can transpose into Grand Prix Sicilian).
modern- Three Pawns Attack (can transpose into the KID Four Pawns Attack)
french- Steiner. Never play anything resembling a French ever again. It's essentially the French version of the Advanced Panov in the Caro-Kann, and it'll leave you with an IQP, but you'll never really have to worry about the 'real' French. Learn the Sicilian: Kramnik just in case Black decides to play 2. c5 instead of 2. d5
king's gambit- Bishop's Gambit, Ghulam Kassim Gambit, Salvio Gambit, Kieseritsky Gambit, Allgaier Gambit, Muzio or Double Muzio Gambit. Against Queen's Knight, transpose to Vienna Game: Max Lange, Vienna Gambit (the better of the Vienna Gambits) and against Macleod, transpose to Vienna Game: Max Lange, Vienna Gambit, Knight Variation.
carokann - Advanced Panov, Toikannen Gambit.
alekhine- Lasker, Four Pawns, Krejcik, or Scandinavian.
nimzowitsch- Declined or 2. Nc3 and hope you don't get baited into a French. More your attacking style is 2. d4 and try for Scandinavian, Bogoljubov, Berlin, Richter Gambit. If Mikenas, treat it like a better Alekhine's and do the Four Pawns Attack formation, and if Kennedy, Linksspringer, Paulsen, Riemann, or you could also just transpose directly to a Scotch Game at that point.
sicilian
Exactly.
Actually, I don't really know why, but I absolutely HATE the sicilian defense.
Do not ask me why, I don't know. 
c5
What??? No Center Counter Defense?
Most you e4 players throw some serious hate my way... what gives?
e6 or e5
and sometimes with weak players in bullet c6
I play the French Variation of the Sicilian Defense against 1. e4. It blunts it a bit when they see what looks like a Taimanov or Schevenigan but now the game changes significantly.
For me the most difficult to face is clearly the sicilian. Which makes it the most annoying.
Second place probably goes to the french, because white can't avoid it and it's hard to get much interesting happening against it. Still, white usually gets a good position so I don't really mind too much.
I play the Vienna so I don't encounter the Petrov. CK I am thrilled to play against. If you hate facing the CK... I think you just need to study whites options, there are many good ones.

The center-counter is a joke.
If everyone played the center-counter, I'd be an e4 player.
The Alekhine Sucks, but I have trouble with positions featuring the big, mobile pawn center, and hence why I hate the Grunfeld and Alekhine, but that's a personal issue.
The REAL problem with 1.e4 is 1...e5!
I'd say Sicilian Defense, Ruy López Opening: Morphy Defense, Alekhine's Defense and Pirc Defense.
I like open and not complex games, and I don't want my Bishop to be kicked (I'm a Ruy López player). 
And I hate Sicilian because I don't want to trade my d-pawn for c-pawn, also I can't play the Ruy López. 
Anything that isn’t e5 or e6 or d5 or c5 or c6 or Nf6.
(but maybe not Nf6…)
