Why a Jeep Owner Is Being Sued for a Mechanic's Death During a Dealership Oil Change

So the dealership had an employee who they allowed knowingly or through negligence without a license to drive a vehicle, and one he did not know how to operate that ended up killing a co-worker and someone how the dealership and it's management have no legal responsibility? The owner of the Jeep although will not be at fault but I would assume he/she must get an attorney to sort the matter out, who pays for that and the subsequent issues he/she may have with their own insurance company? Something seems messed up!
