The members of an LLC would only be liable for debts of the LLC resulting from loans in the following cases:1) The members can be shown to have personally guaranteed the loan.2) The "corporate veil" can be pierced, and the LLC can be shown to have been basically a pretext, created or used to attempt to defraud creditors. This is very difficult to do and is very rare--it essentially never happens if the LLC was a "real" business. (Even though an LLC is not a corporation, since this doctrine developed first in the context of corporations, the term "piercing the corporate veil" is used for LLC's, too.)
