The dub can't even get its credits done properly... figures...

Well, since Ginrou is a minor character, it's unlikely that he'll be credited on the official site. Your best hope would be to ask the SAO USA facebook (https://www.facebook.com/SwordArtOnlineUSA) or twitter (https://twitter.com/SwordArtUSA) accounts to confirm the voice actor. Otherwise, there isn't much chance that a reliable source will ever appear. Unless you're really lucky and somehow get one. Worst case scenario is to find a place where Diskin himself claims that he got the role.
