Will oxygen therapy help my grandma who is 65 and has blood clots in her legs?

No. Unless she has clots in the lungs causing hypoxemia (low concentration of oxygen) she does not need oxygen (which is toxic).
Possibly. The best solution would be to dissolve the clots. Hyperbaric oxygen could be used to get oxygen to ulcerated hypoxic tissue caused by blood clots while the clots are being broken down.
