When someone asks "What do you do for a living?" they want to know what kind of work you do.
You can say:
I work for the XYZ Company.
I am self-employed as an artist.
I am in partnership with Mr. X and we manufacture cars.
or . . .
I am not employed at this time.
Is is OK to ask?
Yes, it is OK to ask, "Is that how you make your living?"
