Chiyo's only good use is generating chakra for characters like Tendo with 80+ chakra consumption. This is literally her only good usage otherwise you should forget about her, she's no good in any stage of the game, her chases deal absolutely no damage and she's going to be completely useless if she gets paralyzed.

If you want people to help you with teamcrafting you need to provide a screenshot of yourr roster otherwise we're left with nothing to work with. I suggest you use this http://naruto.rednubes.de/# to experiment and see what would work and what not. Just make sure you have some form of hard cc in your chase chain and you should be fine.
