What do you consider "seemingly useless"?  If the top part of a pitcher 
is dead but the bottom is still alive it may not be catching any more 
insects, but it is still digesting the ones it already has.  If the 
entire pitcher is dead but the leafy part (I think it is technically the 
leaf petiole) is green it is still carrying out photosynthesis and is 
useful to the plant.  If the leaf is dead or yellow it should not affect 
the plants growth.
