I think there have been a few solutions posted to this before! It's probably just because the hole is there, that she is chewing at it. I would go with having the water bottle elsewhere and blocking off the hole - I can't remember where the thread is, but I think Vectis had photos of solutions (nut and bolt through the hole to block it?) I think someone else did something similar with a screw in carrot ledge
(If anyone can find it that would help!)
I do think a bottle is best if at all possible - much less chance of lost water (spilled) or it getting contaminated.
You could make a bottle stand for the bottle - there are a few ideas for bottle holders on this thread

Another idea on here using an upturned paper cup

Don't get one of those ceramic ones on ebay though, they are supposed to be a bit of a hazard.
Rodipet make wood ones but they're expensive. Living world make a tall wood one but it only holds their bottles and is difficult to fit in due to the height.
I think I'd go with the plastic jar/bottle with the top cut off and weight down with stones inside
Although the stones would need to be clean obviously.

Or one of these lava ledges might do the trick - I've had these - help keep nails short. I used to put a treat on it

Or instead of a bottle stand you could just velcro the bottle on the inside somewhere else.
