I started playing LoL with Lucian in his free week, and later I played mostly Tristana & Caitlyn (Kayle is when I switched to "mage" champs). Hence I know ADC builds in general.

I tried AD builds on Kayle as solo laner and as AD carry before, even tried hybrid builds (Guinsoo+Gunblade) on ADC role. I don't know what your assumptions come from but from those experience I know the Thornmail dmg can be mitigated by lifesteal (or stacking MR&HP), but as Kayle already needs CDR and AD for AD builds, there's not much room for lifesteal and crits - which is important to AD Carry champions.

.

Thornmail reflects physical damage from basic attacks (before amor) - and including on-hit effects. So when BoRK applies lifesteal, its damage will be calculated for the dmg reflected by Thornmail.

Of course the on-hit damage of Wit's End, Nashor are not reflected by Thornmail because they are MAGIC damage. Statik Shiv's proc is not reflected by Thornmail as well, but SS can crit unlike Wit's End and Nashor damage.
