It’s doubtful her guardians will do anything like sue, but I will try and talk them into asking a lawyer
Ultimately it’s up to the parents/guardians, but if this impacted her in more than a transient manner, if issues related to it are still cropping up and haunting her, then it can’t hurt to suggest looking for both sensible child counselors AND (inasmuch as it isn’t an oxymoron) ethical attorneys. Something has to pay for the counseling. If it’s a health insurance company who paid, in fact, they might have the right to sue on her behalf whether she wants it or not.
