ESRB actually rates DLC if it's inconsistent with the original rating of the product. If Snake was considered too violent for E10+, they'd actually have to pass him by them.
But I don't actually know if Snake would actually warrant bumping it up a tier.
Doubtful wasn't it Wario who caused more of a problem on the ESRB than snake for Brawl.
