I think that most airfields charge for a landing or a touch and go. It is irrelevant whether or not you get out of the aircraft. You are taking up circuit space and probably their radio service.
At my local field, and many others, you can ask to do touch and goes and you can then pay on your return to your home field.
Of course you could do an approach and go-around without touching down. However, it is not considered good form to do what you seem to be suggesting and not to pay.
