Without knowing more about your situation, I can only state the obvious which is that the person who owns an LLC is not the same entity as the LLC. A bankruptcy of the owner leaves the corporation and its debts intact. Whether that is satisfactory in a particular situation involves many issues and requires expert consideration. You need to consult with a qualified bankruptcy attorney in your area.
As an addition to my colleagues earlier response, the sole member, if he/she files personal bk, may discharge obligations arising from personal guaranty(s) which were executed by the SM, in his/her individual capacity, in conjunction with loan(s) received by the SMLLC.
