I agree. Although the hitch and ball do form a connection between the tug structure and trailer frame, this is not a reliable or appropriate ground connection.
Andersen offers a line of
nylon-capped aluminum balls, which (in addition to not requiring grease) clearly do not provide an electrical path... which doesn't matter, because - as Jim said - there is a wire for that.
