iirc you can null/counter her insect skills, but trying to stop her magic attacks will set her off.
Also don't use time magic against her either, it's a bad idea.
Beyond that it's not too hard to handle her, thankfully.
Use the Singing or Medicine Skills that remove the (status) Guard Kill Debuffs and apply All Status Immunities, as she has a random chance to reapply Mind Guard Kill at the start of every round. Use Doping to increase Max HP along with the Dancing/Singing/Shield Captain skills that will help reduce damage to let you absorb her hits more frequently. Target her weakness or create one with guard kill and taoism if you need to. Aim for combos. Don't try to rush her, that's going to get you killed in most calamity fights.

If you're feeling lucky enough, it's difficult but possible for you to reflect Mind Guard Kill back onto her when she tries to activate it at the start of the fight or any subsequent time afterwards. If you manage to pull it off, doing so will completely strip her of her own immunities to confusion and sleep for the remainder of the fight and the result is Hive Mind turning into a complete joke who you will effortlessly stunlock and steamroll into oblivion even if you aren't aiming to OHKO her.
considering what happens afterwards I'm genuinely convinced that this was actually the way trtr intended for players to beat her.

Good Luck anon!
