Late game in teamfights Illaoi has no way of setting up tentacles or force the fight to happen where her tentacles are (when in lane the opponent is forced to stay in lane and deal with her tentacles or lose a lot of gold/exp)
This forces Illaoi to rely on her ult (as the tentacles are the majority of her damage and healing)... and if the enemy should disengage after Illaoi uses her ult (and Illaoi has no good tools for sticking to targets).. and fight when Illaoi has it on cooldown there really isn't that much Illaoi can do

Late game Illaoi: 1 E on carry = dead. Anyone else just sets up tentacles + instant half to 3/4ths their life.
You don't really . . . disengage a late game Illaoi lol. Late game she can flash R + triple turret dive and still tank all the damage.
Her actual struggle is in early game because she's gank bait like Yasuo.
