I don't think it crosses the line to copyright violation until he starts making artwork and stuff of the character as his OC it is at that point that LEGO could take legal action if they feel it's necessary. But heck I don't work in law so what do I know? :p

However I do know that the opposite is also true, LEGO (or any company for that matter) can't take your OC and and turn it into an official character without your permission because if they do then they're the ones that can get into legal trouble.
