Hello jiffybag!
Preflop
I mean that's an interesting questions. The hand is profitable as default. I would be careful for you not to overvalue singular hands that went to showdown when you change your defaul gameplan - calling off AKs isn't exactly bat**** crazy 
I'd consider the blinds behind you - if they aren't squeeze happy it's perfectly fine to open the hand and not change usual ranges.
River
Hey I get it, I really do - he is too loose and passive, seems like he is going to check back a LOT - it's a nice bet for value, n'est-ce pas, pardon my French for some reason. I actually went commando and see if solver could approve. My hard disk is being a diva so I made this from scratch, with just one size options
The Solver doesn't like leads here even at puny sizes
Spoiler
Why that is? Well basicaly on the flop we just bet most of our strong stuff and are now somewhat capped
This is flop bet strategy
Spoiler
River nodelock
Ah what the hell, I nodelocked, removed most bluffs
chopped up villain's River buff range
Spoiler
And wouldn't you know it THE SOLVER DOES START TO LEAD HERE
to 18% size
River pro lead with arbitrary commando sim

Conclusion
- His ranges will be way wider than what I used - but you need to be careful not to extrapolate too hard from small samples - the info you gave was vague to say the least
- If you wonder why no T♦:8♦: on the River it's because it folds it vs the turn bet, calls T♠:8♠A♠ it unblocks some backdoor bluff hands from either street.
- River lead isn't terrible or anything - pretty far fetched and unnecessary, but vs small lead he is SUPPOSED TO RAISE 44.5% of the time and if you are right about your reads he shouldn't bluff that often - and if he won't maybe you can even size up a bit as he can call much wider than solver with a wider range
So I mean yeah - unnecessary to lead here unless you really can
- Confidently cap his range because of turn size
- Really assume he is passive and won't bluff enough, both in betting when checked to and raising when you do donk
=> I can see leading here with some extensive reads vs someone very face up ish in a very specific situation
=> I spent way more time trying to science out a way where we can lead in this spot, and 99% most likely so did you. This turn sizing is very unusual and you might take months before you face this line again.
Fun though
