Pretty sure contacting Blizzard legal team would be dumbest thing ever because you'll never get an answer or just get youself in trouble. Best solution is to remove current repository (or make it private) and then create new repo without copyrighted stuff.

That, or remove said assets and scrub the history.. as another thread mentions there are sites with open game assets that can be used... or simple sketch patterns and generated voice assets can be used in the interim until better assets can be released.
