I'm a minority owner in an LLC (15%). How can I leave the LLC (transfer my equity) so that creditors will not go after my personal assets?

We are a New York State LLC. An LLC (4 members, 60%, 10%, 15%, 15%) files for bankruptcy. We are vulnerable to creditors “piercing the corporate veil” because there have been mixing of personal and business accounts. 1) All the remaining business debt, does it get distributed evenly to all the members, or proportionately, or only to the majority? 2) Post filing for bankruptcy, can a creditor go after the minority members if they have not gotten all their debt paid from the majority member? 3) If a minority member decides to leave the LLC before the company files for bankruptcy, could their personal assets still be targeted because of their previous involvement, or are they totally clear?
