In general, the taxpayer ID used to open the account is the taxpayer that owns the account. I am the treasurer of a small non-profit, and the non-profit's EIN is listed on our checking account. Having my SSN on there--except as identification that I'm authorized to perform transactions on the account--would have made me an owner, which is not what we wanted. Check with your bank to be certain, but I would change the account's EIN to your LLC's.
