AK against L-P Villain

[JustToast]

In this hand, Villain is 51/0/1.36

I have not noticed him much so far except that he is loose.

Flop: wondering if he would raise a draw or had two pair. Decided to call and see what he does on the turn.
The turn bet was following that same thinking and seemed fairly weak. Re-raising all-in here was a thought, but decided against it as I was concerned as he's so loose he could have anything.
His river bet seemed big enough to be not wanting a call... so I called.

I really don't like the line but I don't see how to get more information out of a guy this loose.
