Villain and I each have double stacks.
I'm dealt [As][Kc][Ks] in 2nd position. UTG limps, I raise to $2.25 and all 5 players call.

Flop is . Checked to me, I bet $10, Villain on button raises pot to $43.

I have $88 left and Villain covers.

Is this an easy fold?
I'm very new to PLO so please take into account before tearing me up.

If you're confident he would only do this with a set it is a fold, if he could do this with 2p / wrap (like I would, maybe why I run so horribly) it's more towards a push:

vs. the monster

pokenum -o 8c kc as ks - jh jd td 9h -- 4h js 8s
Omaha Hi: 820 enumerated boards containing Js 8s 4h
cards win %win lose %lose tie %tie EV
As Ks Kc 8c 274 33.41 546 66.59 0 0.00 0.334
Jd Td Jh 9h 546 66.59 274 33.41 0 0.00 0.666

But this is where it gets more interesting...
vs 2p + draw

pokenum -o 8c kc as ks - jh 8h 9c tc -- 4h js 8s
Omaha Hi: 820 enumerated boards containing Js 8s 4h
cards win %win lose %lose tie %tie EV
As Ks Kc 8c 439 53.54 381 46.46 0 0.00 0.535
Tc 9c Jh 8h 381 46.46 439 53.54 0 0.00 0.465



On this board against an unknown oppo I think a fold is correct but with more info I *might* lean toward a push.
