5nl 6m AA vs donking fish

Villain is 43/11, 3b 5, 3.1AF, 42% Agg Freq over 80 hands. Likes donk betting, for example: in the bb vs button raise, flats 89o, donks 1/3rd pot on TJ3tt flop and calls 1.5x pot sized raise (all in) from his opp

His post flop aggression is very high for such a vpip. Looks like he bets small with draws and weak hands, but in another hand I've seen him pot every street so it looks like he bets big with an actual hand.

Also seen him donk small on other occasions and bluff A high otr for 1/3rd pot with a baby flush board when his opp checked to him with a medium flush.

CO ($4.84)
Button ($4.79)
SB ($6.10)
BB ($5)
Hero (UTG) ($6.93)
MP ($2.25)

Preflop: Hero is UTG with A, A
Hero bets $0.20, 3 folds, SB calls $0.18, 1 fold

Flop: ($0.45) 7, 3, 9 (2 players)
SB bets $0.45, Hero raises to $1.80, SB calls $1.35

Turn: ($4.05) 5 (2 players)
SB bets $4.10 (All-In)

I am having some difficulties putting him on a range here. If he has a flush draw otf, then he is betting it more aggressively than usual (not impossible if he also has 2 overcards or a pair of 7's to go with it, I guess). If he has a set or two pairs, he should shove over on the flop but who knows.

Does he ever turn 88, TT-QQ, 9x into a bluff ott, esp. if he holds a diamond?
