uhmm... I think I would refrain from forcing anybody who are not trained in ukemi to take a kotegashi fall. Especially if it's outside of the dojo. Quite a big risk of hurting them badly.
I find that kotegaeshi is a technique that you can apply rather vigorously even on beginners if you dont focus on the wrist twisting. After all, the "fall" is only a balance break from standing and you can dampen the impact with the arm you are controlling.
