What are you thoughts on the Kings Indian attack?

In your specific situation, it is OK.  Same thing goes for the Sicilian with 2...e6.  1.e4 c5 2.Nf3 e6 3.d3.

Most other lines, it is ineffective.  That said, you REALLY have to know what you are doing.  There is one guy at the club I play at that plays the KIA against the French, and he has failed every time.  See below.  Each have a different issue in the opening and each suffer their consequences.  With correct play, it should be dynamically equal.

That said, you have to know what you are doing or you will get killed like in these 3 games.  In the first one, White made the fatal mistake of going 11.Bf4 and 12.Ne3??.  He needed to play 11.h4 and 12.N1h2 followed by 13.Ng4, 13.Ng5, or 13.Bf4 (which is why 11.Bf4 was OK but inflexible).

That game was played April 27th.  Here was another against the same player on February 2nd.  In this one, he fails to play e5!

And lastly, back on November 17th, his error was on move 14.  As you can see, there is very little room for error in this opening.  I have gotten beat with it, but usually only against extremely strong players, like I lost a game in Kansas back in 2018 to the top seed.  But here, failing to take the knight on move 14 gave Black an excellent post for the knight and white crumbled fast.

RoFL 🤣 Is it really King's Indian Attack ?!?  🤔 It looks rather like Declined Scandinavian or maybe French. 

If you play the King's Indian Defence as black then it is quite good. Example:

I don't quite understand it but maybe I'm just too much of a plebian to understand

Lol lets pretend we are not currently playing that opening...

Roll on the floor all you want!  It IS a King's Indian Attack.  In fact, you get the exact same position from 2 move orders!

1.e4 e6 2.d3 d5 3.Nd2 Nf6 4.g3 c5 5.Bg2 Nc6 6.Ngf3 Be7 7.O-O O-O 8.Re1 b5

1.Nf3 d5 2.g3 c5 3.Bg2 Nc6 4.d3 Nf6 5.O-O e6 6.Nbd2 Be7 7.Re1 O-O 8.e4 b5

This position would be found in A08, not C00.  It is a King's Indian Attack!

So before you laugh, maybe next time you should know what you are talking about first!

It's not a Declined Scandinavian because after 1. e4 d5 2. d3 Black would simply swap Pawns and then Queens instead of playing 2. ... e6.

1. e4 e6 2. d3 is indeed the KIA. I used to play it a lot in OTB tournaments.

Nobody does! Well. Fischer, Kasparov, and a few other weirdos

There is some inferior play in the low teens.

12.Bf4 - "OK" but lacks flexibility.  12.N1h2 is better.  Now after 12...Ba6, White can play 13.Bf4 (hence why 12.Bf4 is not bad, just inflexible), 13.Ng5, or 13.Ng4.

13.Bh3 - Inferior, Black should never plan on f6 until way later in the game.  There is a line with f5, but never f6, and not when White can enpassant.  For example, in the line with 13.Ng5, Black has 13...Qe8 14.Qh6 h6 with a future ...f5 when en passant will not be possible as the Queen will be hanging.  White will be forced to trade Queen's.

13...h6? - This does nothing but creat a hook.  Black should be continuing on the Queenside, like 13...a4, for example.

At first sight 2 d3 looks inferior to 2 d4, but this is not. White gets a King's Indian Defence with an extra tempo and black has committed himself with 2...e6, whereas white can play e4 instead of e3 in the King's Indian Defence. So it is rightfully called King's Indian Attack, as white gets a dangerous attack on the black king. That is why attacking players like Bronstein, Tal, Fischer, Kasparov liked to play the King's Indian Attack.

It is still only dead equal with best play.  White does not get a raging attack if Black knows what he is doing.

Yes, it is just one of many openings that is drawn with best play.

All sound openings lead eventually to equality. That's what makes them sound openings.

I don't believe there is any point to it at all. It looks to just give black at least equality straight away. 

Is that supposed to be some kind of amazing observatione? Everyone knows with perfect play it's a draw for both sides, the problem is that with the KIA it's a draw right off the bat.
