Unlikely, it's not as if the company simply failed to get authority to do business in the state, but it was an LLC otherwise. It misrepresented its limited liability status. I'd speak to an attorney, like myself, regarding your matter.
The answer provided is for general information purposes and cannot be relied upon. In order to provide legal advice, one must engage with a live attorney; this answer does not create such attorney-client relationship.
The LLC would -- possibly -- shield him from liability, only if it existed. If he engaged in bad acts before the LLC existed, setting up an LLC would not retroactively protect him.
An LLC cannot shield an owner from personal liability for criminal conduct.
