I'm probably missing something. wouldn't white have been fine after 9.kg1? was there any sort of forced mate or way to get back your material?
I made a beautiful sac to end the game in 9 moves!

That would actually end in mate because after 9.Kg1 10. Qb6+ Nd4 11. Qxd4+ Kf1 12. Qf2#

I would’ve won material back no matter what move he made.

Very nice and an excellent demonstration of why f2 or f7 need to be carefully guarded, especially early in the game. Fred Wilson, one of highest ranked Seniors (2200+) in USCF chess, wrote an excellent book, Simple Attacking Plans, where his 4 principles are demonstrated by 36 annotated games and this game is a good example of his first principle:
I have come to believe there are only four essential, even primitive, concepts which you must learn and understand in order to play successful, attacking chess - Fred Wilson
- In the opening, whenever justified, relentlessly attack the weak squares f7 or f2.
- Most successful kingside attacks are directed against the squares h7 or h2, and they are often preceded by eliminating or driving off its defender. Corollary: most successful attacks require a long queen move.
- If your opponent’s king is trapped in the center, make every reasonable effort to open and dominate the e-file, and sometimes the d-file also.
- If possible, point all your pieces at your opponent’s king.
When I'm in a game where I don't know what plan to follow, I mentally review these 4 principles and I've raised my rating 100 points. I've become more aggressive - which has led to more good results than bad.

Why not . 9. Kf3?
What is time control? Human may miss such critical queen trap in 1 min bullet though.

It is common that human sometimes blunders in opening in bullet/blitz.
It was the game I played in lichess, 2000+ rating, in 3 min blitz.

Just looked at what the chess.com engine has to say. 8.Qb6+ 9.Ke1 Ng4 10.Nc4 Qf2+ 11.Kd2 Qxg2 . e4 looks like it'll fall also. A more horrible position for White than after Qf6, Nf4 in the other line which seems to not be quite as over for White as this line.
To play Qb6+ though I don't think this line even needs to be seen. All you need to know is that you're giving your opponent one less unclear option (Kf3). In the other lines it transposes back anyway.

This was in a 10 minute blitz game and it happened fairly early, maybe with both of us having over 8 minutes left. I know most 1500s would fall for this trap but maybe a 1600 would be more skeptical of “free” material. During the game I saw the result of all his possible moves and I knew the least favorable for me would be kf3 but I also knew at bare minimum I would win back material and expose his king completely which would be an easy win.

I took my time thinking about this decision in the game and I still decided ng4 because I knew I would win back material and I would expose the king very early in the game and it was very likely my opponent wouldn’t even consider kf3 because of that. The possibility of a forced mate or winning the queen was very likely and worst case I would win a knight with some ideas to continue my attack but you’re right if my opponent could see this coming then qb6+ would be the better move.

I’m actually really happy you brought this up. I always had an idea of these concepts but only from experience. I will definitely be looking into this book soon. Thanks!

I’ve been playing horribly and infrequently as of late so I think I’ll share a moment of brilliance that I’ve had. Let me know what you think.
Nice game. My daughter played black in a game that followed this exactly up until move 9.Kg1 in a scholastic tournament where they played to mate.
Your daughter plays the Caro-kann? Smart girl!
