wtf this river could hit villain very well. however you already put half your stack in so just shove because villain will check behind a lot of hands you beat

This might be nit-picking, but I'd really prefer a full pot on turn. Push river and get some value from 2-pair, smaller sets. Of course, sometimes his straight are going to be made, typical of omaha ldo, but you can't let him check this river. If he hit his straight and bets pot you're going to be calling anyways. So by checking we allow him to get out cheaply when there is value there.

Another option is to bet less than pot. There is value here and I think full pot is a little too scary. Maybe $35

Bet/calling is gross. I'm slightly drunk, so my response won't be too detailed, but I probably prefer a check/call here to induce bluffs and stuff.

just over half of UTG's stack is already in the pot

stick the rest in easy

I'd make it $25 and call shove ofc.

villain depended, I prefer check/call here if villain is aggressive.
in my opinion you are not gaining much from betting. 7s and 2s pushing / folding flop.

check looks a lot like you missed your nut draw and gives villain tons of FE over you in his eyes. he is river betting with a very wide range.

wow this hand is weird, + you have Ace of hearts
pot turn
river is villain dependent I think, how often does he go to showdown, and is he likely to call river with overpair + fd having not raised turn or flop???
It's 100bb deep, so there is no reason villain would be cautious about any made hand leading up to river that everyone is trying to get value from.
I think he has KK w/ hearts or JT98 w/o hearts probably weighted towards the kings because of your holding, but his line screams more like JT98 w/o hearts.
(not that I could force myself to fold river)
I assume if he thought his overpair was good enough to call this river, then he would have shoved the blank turn.
check/call, as there might be some other odd hands that he's bluffing with, and the kings he'll check behind most of time
