Kenny is practially swearing in all contexts. it's his character. Larry is the same and it fits his heated grumpy character. Lee usually swears when he is arguing, annoyed or something bad happened. Characters like Clem, Molly, Duck, Katjaa, Carley, Ben, Doug etc. barely ever swear, if at all. And when they do it's highly justified by the context (e.g. when Ben is screaming at Kenny). Personally it didn't bother me in the slightest as it was only used when it makes sense it seems.
I'm gonna take Carley and Molly out of your list. Molly may have been PG-13, but Carley had a pretty bad mouth on her.
