I think you are talking about a Jeep Cherokee here (most Jeep models are available in Trailhawk trim). I have a 2020 Cherokee that I flat tow.
You are correct regarding the flat tow harness and the so-called death wobble. That applies to 2018 and earlier, and is not required on2019 and later.
Any Cherokee Trailhawk can be flat towed because the Active Drive 2 drivetrain is standard equipment. It can be ordered in any other trim level of the Cherokee, but it is relatively unusual to find one (mine is a Cherokee Limited that was special ordered).
The collision avoidance thingy you mention is part of the Technology Package option. It is not standard equipment on the Cherokee. It’s plainly apparent if the car has this option,there is kind of a eyeball radar sensor in the lower front grill below the bumper. To answer your question, it has no impact on towing because the Jeep is turned off while towing, so it’s not active.
