Visitor parent overstay issues

[am_tx 0]

Hi all, 

I am asking question just to get some information to help my neighbor(if I can)

There is Indian lady (upper 60's age) who came to visit her daughter/son here in US 6+ yrs ago. and she overstayed her visa may be by years now, and also her Indian passport expired. She is literally living in her daughters house like a house worker. Now with the covid situation everything getting worse. She says she just want to go back india. But her kids are not helping with her passport renewal or any other immigration related. Is there a way she can just book a ticket and go back? I am trying to get some sense what are her options in this case.
