I’m not a lawyer either but I Know a little about the law. Even as an LEO, you have to have documented training hours on less lethal to deploy it. If not, well, you and a lot of your superiors are in hot water. As a civilian, there is absolutely no argument you will win using less lethal on an individual. Also note, it’s LESS lethal, not non lethal. You use that stuff it’s over for you in life.
