A personal favorite response of mine if I don't have any questions left is "no, I think I injected most questions I had as we went along. I was going to ask <thing>, but I think we covered that well already." This is helpful if you're like me and turn interviews into discussions instead of Q&A sessions. It shows you've considered you might not have the full context just from prior correspondence, while resurfacing a discussion topic for them to expand on if they wish.
