Probably a redundant question...

So I have this KA24DE, it has all new seals including new head gasket, but the bottom end hasn't been updated, so it still has the old rings. It has very low compression, as in 120psi in all cylinders, once I add some oil, that jumps to 180psi in all cylinders. So usually that means the rings are toasts. But I've never seen such a low compression before, although it is most likely the rings, could it be something else?

I can't think of anything other than rings that would increase compression after dropping some oil in the cylinders. You've pretty much answered your own question. Time for a bottom end rebuild.
