No. Lifesteal and spellvamp are not considered healing nor regeneration, and are unaffected by all abilities that reduce normal healing/regen. Lifesteal and spellvamp are based on final damage done to champion, if your damage was prevented for any reason (shield, trynd ulti, blind, dodge) you will not gain any spellvamp/lifesteal.
