Yep, that's one of the nice things about Will of the Ancient's spell vamp aura. The AP bonus may not help everyone on your team, but pretty much everyone has at least SOMETHING to spell vamp from. As long as an activated ability deals some kind of damage of its own, spell vamp SHOULD apply (unless lifesteal does).

So having the spell vamp aura as, let's say Taric, will allow a nearby Urgot teammate to heal using his noxian corrosive charge and acid hunter missiles. Even though they scale with AD, they are abilities, and thus spell vamp works.
