Its not marginal to call almost anything preflop versus this sizing from position and definitely not hand like high pocket pair that we can purely set mine and show profit. I have never said villain range is just AAxx. But it will get closer to it with decent sample and practically no 3bets at all. If we have 10 hands on someone and his stats are 60/60/40 can we not make any assumptions? Sure of course its possible guy has just hot deck but more likely scenario is that he has too wide ranges. Or lets say you join table and someone 3bets three hands in row without showdowns. You open and face 3bet from same guy. Could be four solid hands in row but we should really ask which is more likely, 4 solid hands in row or villain 3betting way too wide. This is example on the other extreme side of statistics on very small sample.
Not related to this hand but solver does lot of light calls in lot of spots because it assumes opponent to have very creative bluffs that most human players simply dont have at least in high enough frequencies. Good example could be x-r line in 3bet pot on J55r flop. 99% of players are way too value heavy in this spot when they x-r. Some might turn some Jx into bluff. But solver would x-r-f 45% of time in this example and x-r versus 1/3 pot cbet whopping 24% of time:

So hands like A322 with 3 high bdfd, A432 with two bdfd. Even more logical ones like 9876ds are very often just being x-f. I recently watched video on plomastermind about these paired flops that was on pool in PLO500. There data on pool showed that people are fast playing too much strong hands and not finding even closely enough bluffs making raise range way too value heavy. On those stakes pool in general is more creative and aggressive.

I don´t think we have implieds odds. Villain is not going to bluff a paired river with air but will check-call his top-set when the river brings a flush? Makes no sense to me.
There is simple reason why this can be the case. That is not understanding relative hand strength and/or falling in love with the hand. There are absurd amount of examples of people not getting away from AA in holdem even if board runs very bad. Why? Because its aces, best starting hand available! When player get this idea of "now I am going to win big pot" it can be very hard to let hand go.
Why do we see people calling set or even two pair in omaha without any relevant blockers when board offer flush and straight? Likely because they dont like folding or they just think set is still strong hand. They might not think about any blockers etc. at all in first place. Why does some people play aggro with small flush and isolate themselves mainly versus better? Most likely again because they think flush is strong hand. E.g. in holdem two card flush on non paired board is very strong hand and lot of players come from holdem background to test omaha. So its not that rare to see bad calls.
Good example of overvaluing AA:
