If you're an autorized user on credit card can you roll it into bankruptcy?

No. That credit obligation does not belong to you, you have simply been authorized to sign for purchases made. Think of the example of a corporate credit card. A company would authorize you to buy things with the card but it is not part of your personal finances. You don't legally have to make payments on it, and if the card defaults they don't come after you for payment. Therefore the account is not your liability.
