Will a woman be held accountable if she leaves for necessary and unnecessary family visits without her husband's permission, given that the husband had abandoned the home for weeks, no longer cared for her, and then divorced her?

It is not permissible for a wife to leave her husband's home without his permission, and she incurs sin if she does, unless she is aware of his implicit consent, or in cases of necessity and dire need such as obtaining maintenance or treatment in his absence. However, if the the husband expels her from the house, she incurs no sin by leaving and is not considered disobedient.
