The question has already been answered, but here's why: for a partner to have recourse debt on their K1, for example, that owner has to have an economic risk of loss as a result of the debt. If formed as a partnership and
not an LLC, this automatically holds true since general partners typically have unlimited liability. An LLC taxed as partnership would require personal guarantee or (and very stupidly in an LLC) a deficit restoration obligation, which could result in members having unlimited liability in absence of personal guarantees in same manner as a general partnership (I have seen some stupid lawyers put these into LLC agreements without realizing the disaster scenario they just created).
From my trusty Parker Publishing, and I am pretty positive it is correct to say this applies to general partnerships from a LEGAL standpoint, but not an LLC taxed as a partnership unless that personal guarantee exists:
Reg. Sec. 1.752-2(b)(1) generally provides that, for purposes of determining whether a liability is a recourse liability, a partner bears the economic risk of loss for a partnership liability to the extent that, if the partnership constructively liquidated, the partner or related person would be obligated to make a payment to any person (or a contribution to the partnership) because that liability becomes due and payable and the partner or related person would not be entitled to reimbursement from another partner or person that is a related person to another partner.
