Since the regulation calls for CIP of your customer and the LLC is the legal entity that would be your customer, I would only CIP the LLC.
Just as a clarification, we generally ask for identification (ssn, dl, etc.) for authorized signers, just so that we can assure ourselves that they are who they say they are and 'tie' them to the account, but this is not considered as part of CIP.
