Hello. Not sure what you mean by a Linnmon cage? It sounds like she needs to be in a glass or perspex tank. Glass tanks are expensive in the Uk. You could get a detolf if you have space (£40 from Ikea and needs a lid making but there are lots of tutorials on how to do that). Only thing with a detolf is it has metal bars inside and wood ends and she might chew at those. You could mesh the inside of the end wood parts but the bars could be an issue.
A good option would be a maxi duna multy (perspex tank) or a Zoozone 2 which is cheaper but needs meshing on top as the bar spacing is 2cm.

They have a hole in for a water bottle, which many hamsters chew at but that is easily blocked off with a screw in chew or nut and bolt and then you can either have a bottle stand or velcro the bottle to the inside of the tank.
Alternatively, it might be to do with her current cage. Not sure what cage she is in at present, but if it's quite small that can often be the cause of bar chewing and can stop with a bigger cage. I'll check out your other posts, as some hamsters if adopted can have a fairly ingrained bar chewing habit and then a tank is the best way to go really.
