Akali relies on getting Lich bane so that she doesn't falls off late game, just nerfing this item and not compensating on Akali's ratio is going to make her irrelevant late game, especially since Akali is not even dominant pick like the rest of the champions getting compensation atm, so idk whats going to be scary about that.
Saying that Diana is getting compensation, most definitely means Akali needs one as well since they are both similar champions that have clashed many times into who being the better one (Diana being Akali 2.0 but better). Diana also doesn't rush this item either, she most likely gets Hourglass or tanky AP items first...so this doesn't seems to make sense at all.
This will just be a big in-direct nerf to Akali's Lategame when she doesn't even needs one.
If you had to add compensation, the thing is that Akali does have an AP on hit passive: Discipline of Force, so she does falls into the category of getting compensated for lichbane nerfs.
EDIT: I forgot to mention that Akali is a late game AP hypercarry since she has a weak early game therefore such adjustments will be needed to preserve it if Lichbane is going to take such a heavy nerf due to others making it a problem not Akali.

She certainly falls into the category of champions worth considering. I'll make sure we at least have a discussion about it.
