Liability of the Manager of a Nevada LLC, can someone sue to manager?

Since the Nevada LLC does not require one to disclose its members and only require naming one person as the manager, is there any legal liability that the manager is subjected to? If a lawsuit happens and the lawyers cannot determine who the members of the LLC is, could the lawyer go after the manager? or would he/she just go after the LLC as an entity and the ets ociated within that LLC
