Maybe I'm missing something here, but so long as OP actually formed the LLC, which can be validly done by just filling out and filing state-provided forms and paying filing fees, the LLC by default will have blanket power to do anything legal to carry out its business. The only caveat would be if he stumbled into a regulated industry like banking, insurance, or medicine. Unless he put something weird in his articles, he will be an agent of the company as a manager and/or member. Where is the common law ultra vires risk? In any event, I'm not giving any opinion to OP other than that he should have a local lawyer walk him through his formation process, as mentioned in my other post.
