PLO5 JT98ss

Good question. I think pushing All-In should be fine longterm. That hand runs pretty well in Multiway-Pots.

It´s hard to give the opponents a real range. I´m just a bit concerned about the BB, who has not that megafishy stats and is overcalling here with a deeper stack. He could have sth similar like your own hand, but if you push he should fold some sort of weak Kings and Queens. But also, you can dominate some medium rundowns, that he may call multiway, where you can take at least the side pot.

CO has just 4 cards
MP might have AA sometimes with Limp/raising, what would be OK not stealing our outs

I actually prefer a call here, and see a flop. I like to save some money when the flop comes paired or mono that completly misses us.

It's just one of those spots where you have to call and call some more and hope you hit the flop in some way to be able to stack off. Obviously your hand is too good to fold multiway but if you can not shove preflop that would help since an A22 flop would really suck.
