There's always the option of leaving out the last line if the extra
object is a problem.
It would only mean that if you made changes to Label.prototype at
runtime, it wouldn't affect ListItem.prototype
That could either be a good thing or a bad thing, depending what
you want.
I'm not sure what the problem with the extra objects is, but you
could make your extra objects identifiable by setting the ID:
ListItem.prototype = new Label('protoListItem');
