Ignore her and pretend she doesn't exist
take that to such an extreme that you literally do not acknowledge her presence when she is in the same room as you. The worst she can do is report you for completely ignoring her, to which you can simply say "she was creating a hostile work environment so I was ignoring her for the sake of negating such hostility while doing my job to the best of my ability and not letting her negatively affect my performance with her negative attitude"
