Can a legal kiwi please soothe my ignorance? Getting something like a court ordered psych-eval would be completely off the table, wouldn't it? Since you're already asking for payment, in my legal ignorance it occurs to me that you might also posit the idea that she clearly has some brain troubles. Sure she's a real obnoxious piece of shit but you can't help but feel bad for her (not really ofc), you'd like to see some relief to her greater obstacles in life. None of this would be a bad thing. You know she'd absolutely hate it which means it'd probably be really good for her.
I'm almost certain the answer is no, just making sure.
