I find a resolution and an operating agreement to be two totally different documents. An operating agreement is like the bylaws of a company, which outlines what is to be done. A resolution should be a document which states the LLC authorizes you to open a bank account at whatever bank, and how many signers there should be, etc. If you're the only member of the LLC, you could write the document and sign it yourself on behalf of the entity. (Legally, it is a seperate entity. Whether you chose to have it taxed as a seperate entity [corporation] or not [sole proprietorship/partnership] was your decision.)
