I think you are confusing a lot of unrelated things. She encouraged and manipulated a person into doing harm... Just because the harm was to himself makes no difference.
Charles Manson personally killed no one, but he was properly convicted of 7 counts of first degree murder.
There is no confusion in the law about this. She should indeed face these charges.
Difference between inciting others to murdering and telling someone to kill themselves.
What does the un-confusing law actually say about this particular case, in context?
