At this point, it is time to file an extension. No tax will be due at the partnership / LLC level, but don't add the additional pressure of thinking you MUST get the return done immediately.
Get an extension filed for the LLC and keep in mind you may need to extend your personal tax return as well. Nothing wrong with filing an extension.
