I already created a list of similarities between the two champions to support my case (I assume that you already read through the concept for Aerith). Here are the similarities:

_ Kai’Sa and Aerith are both AD Carries.

_ Both Kai'Sa and Aerith has a (Q) ability that automatically targets nearby enemies

_Aerith’s (Q) deals doubled damage to champions. Kai’Sa’s (Q) deals doubled damage after it is evolved.

_ Both champions have a (W) ability that fires a long-range projectile, revealing enemies hit.

_ Both champions have an (E) ability that must be channeled for 1.5 seconds before use

_ Both champions have an Innate ability that is inspired from Jhin's innate: Aerith has an ammo system, while Kai'Sa deals percentage missing health on targets with 4 stacks.

_ Both champions have an extremely long dash: Aerith's (E) and Kai'Sa's (R)

_Both champions have an ability that gives both defense (shield) and offense: Aerith's (Q) and Kai'Sa's (R)

_Both champions have AD and AP scaling and deals mixed damage, which gives them flexible builds.

_In her alternate skin, Kai'Sa wears a mecha suit, armed with jet packs and a gun. Aerith also has a mecha suit, a gun, and jet packs

_Both champions lost their parents as a child, and have no memories of them.

Here are more evidence: I remember that Riot posted on Youtube a while ago. In that video, Riot developers said that it usually takes 12 to 18 months to create a new champion. Now, let’s look at the date of Aerith’s publication (May, 2016), and compare to Kai’Sa’s debut date on the PBE (February, 2018). The two dates are 19 months apart, which makes me believe that Riot was developing Kai’Sa using Aerith's concept.

While it is unlikely that Rito took inspiration from my work, there are too many coincidence to refute the theory.
