So as I understand the ICE world, manufacturers have been continually challenged for decades to increase fuel economy. In an effort to meet those goals they fine tune their car designs to lighten up chassis, body, suspension, HP ratings, brakes, etc. to meet the needs of moving the passengers, and some small payloads. If you look at the specs on many compact vehicles, the load of four adult passengers nearly max's out the total vehicle rate load.
So basically most US auto manufacturers aren't designing compact and midsized sedans to tow, as this requires greater strength and weight for the vehicle which is a fuel penalty for all use. Their answer to towing, is they all sell SUV's and trucks which are purpose built to have tow capacity, and have the torques, chassis, and brakes to withstand these extra loads.
We all know BEV's have great torque, but they also need the chassis, suspension, and brakes to be able to handle the demands of towing, without having to overbuild the vehicle for the minority who need to tow with a compact sedan. By putting a factory hitch on a sedan, a manufacturer warrantees that the vehicle can safely tow some capacity, and assumes product liability for same.
