construct attributes say it's not subject to energy drains...but in the dmg it describes energy drains as something that leaves a negative level, which vampiric touch does not.
it does say "one living creature touched" but isn't a shield guardian "magically alive"? it doesn't have a constitution score, but couldn't you vampiric touch a vampire? they don't have constitution scores.
anyways, i'm asking cause i'd love to use vampiric touch on my own shield guardian cause he heals so fast. short of that, i'll have to have my guardian keep a troll for me to vampiric touch 3 or 4 times before battle =)
