Legal Question in Intellectual Property in Illinois

This is too complex for this forum. Assuming the LLC actually owns the TM (and it varies depending on whether we're talking state only or federal registration), then you must look at the operating agreement to determine who has the authority to sell assets. Many operating agreements provide for member concurrence at some level for "major decisions" and if the TM constitutes a major asset, that might be the case. So first someone must look at the operating agreement and then at the status of the mark; without doing so no workable answer would be appropriate.
