I've tried many builds, and the reasons I see AP build is generally better than AD are:

1/ The on-hit effects of items does not crit (+100% dmg), and also not for spell-vamp (only magic dmg from E is counted for spellvamps, and the splash count 1/3). So Kayle can not afford building AD along with CDR, lifesteal and AS - some must be sacrified.

2/ Thornmail, which reflects damage before armor to magic damage. Against tanks with Thornmail, the AS builds (like Runnaan) are nearly to suicide - with 200 armor per 100 physical dmg from Kayle, they receives 33 HP lost, meanwhile Kayle receives 30 magic dmg (and with 30MR it's like 24 HP lost). Most of the time Kayle won't build AR pen or MR pen until late game so with stacking HP the tanks can target Kayle and zone her out of teamfight - or even kill her.
