Lee Sin Late Game

Everytime i end up as a jungler i always pick or (mostly ) and I noticed that, doesn't work out, in early/mid game you steal buffs, do dragon, kill enemies easily, gank, and deal a lot of dmg, get objectives etc,

but then in late game, you become literally the weakest Player in the game, i feel like you don't deal much dmg or really can't do anything, the best thing you can do is just Flash and Ult their adc (or anyone rly) into your team to kill them. I mostly build with something like this

(Or )

am I building something wrong or what idk, please let me know.
