For one thing a 1099-MISC has nothing to do with it because only businesses issue 1099-MISC in the course of doing business.
Secondly, it does not seem to be an employee-employer relationship since the grandmother is receiving the service from another relative that is getting paid (by what I would consider to be non-taxable or reportable gifts) from other relatives.
I would suggest that the relative that has concerns about this consult a tax professional for advice since they probably will not listen to anyone else.
As far as I can see there is nothing here for anyone to report on a tax return.
