I have a volunteer sunflower. When digging it up for the winter, I discovered rhizomes instead of roots. Does this mean that it is an edible sunflower and the rhizomes are sunchokes or Jerusalem artichokes?

Most likely, yes. I would be careful though. While sunchokes are tasty, they can become invasive quickly. 1 tuber can produce up to 20lbs of additional tubers in a season. So they can quickly take over an area.
