Bet bigger on flop bc there are a ton of hands that will call you on that board.  I think the turn is fine since I'd hate to reraise and face a ship in this spot.  The river seems like a spot where I'm raising since his bet is so weak.  If he's decent he should know you have a hand after calling the turn and is rarely inducing in this spot.  If he's calling a raise with all sets/2 pairs then it seems like making it 1100 in this spot and folding to a reship is best.

Well, if it's unlikely he's bluffing you have to decide a few things.

1) How thinly is he ch/r'ing the turn+betting river for value? 

2) How many better hands will fold if you raise?  How many worse will call?

It seems like a clear call getting >6-1.  It seems ambitious to expect a lag who's stuck and just block bet a flush river to be bet/folding better hands.  I'd just hope he has worse here ~15% of the time or w/e.

i don't think this is very complicated at all -- turn is easy call, riv is sigh call and I think he has a straight most of the time

From what i understand of you labelling him as a LAG is in a respectful way.
Based on that, it is probable that he is calling a lot of suited connectors, middle pairs,middle and high jumpers( AQ, KJ, Q10 , J9 , and so on). 

Now he might call on the flop with made hands like TTP(very less probability as only 3 combos)/set of 9s( again only 6 combos) but these hands can be slightly discounted as their chances of hitting the flop are low and you would be facing a check-raise on this flop if they had these hands/ flush and straight draws are calling along with 9x

The 10 popping on the turn is not entirely a bad card. although JK and J8 reach there , there are whole other hands like 78d, AJd, Q10( 3 combos),9 10 ( 9 combos) for which the turn is an improvement and given his bet size is not particularly keen on drawing value from you. Shipping here again depends on effective stack sizes after he check-raises.(IMO you should be ahead mostly given his flop calling range).

On the river, since you avoided shipping it on the turn, this should be an indifferent call to the bet.

Is sb the type of lag that would raise the majority of his flushdraw combos otf? 

answer to this question helps us define his turn raising range a lot better. 

also, you mentioned villain is a LAG player, how does he view you? are you a tag? lag? do you cbet a lot? not a lot? if you raise turn big will he think you have flushdraw combos in your range?

You should bet the flop bigger. There are a bunch of SDs in Villians range, and a bunch of pairs that won't fold. You need to get in money with these stack sizes. About 170-180.

Turn: Bet-calling looks fine. A titling LAG can easily have a lower set, two pair, or a made hand turned into a bluff. He should never have J8, so you only lose to KJ.

Reads are very important in a spot like this. If he had a flush draw, he probably would have c/r the flop, not the turn. More likely he has a value hand that's not a flush.

And since you beat every value hand that's not KJ, you should call. The hands above don't call to a raise, and a tilting guy will not fold KJ here.

Call.
