I'm not sure what your question is, but if your LLC is dissolved, you certainly don't need to file a bankruptcy for it unless it has a lot of assets that need to be liquidated.
LLCs do not receive a discharge of debts in a Chapter 7 case anyway, so not sure why you think you need to file bankruptcy for it. If it's dissolved you clearly are not interested in doing a Chapter 11 reorganization.
If you have personal liability for any of the corporate debts you may need a personal bankruptcy.
