I'm not certain of this, but I think champions with negative AD, not only do no damage when they auto attack, but they actually hurt themselves. To be more precise, they receive damage equal to their negative attack damage, as MAGIC damage. (Example, -20 ad means 20 magic damage for the attacker, per attack)

I'm not totally sure about that, but that's the only explanation I can give, for some of my games as Tryndamere, where I had absolutely no way to deal magic damage to any enemies (Neither Nami's on-hit, no nothing), yet by the end of the game, I always seem to have dealt 150-200 magic damage.

So, that's my quess. Negative AD returns as magic damage to the attacker. (Haven't tested that   'professionaly')
