:no I have worked as a guide on a dive boat out of Key Largo, every trip with that company was a guided dive. Every dive boat in Hawaii does guided dives, you would have a very hard time not doing a guided boat dive here unless you rented your own boat.
Before you speak for the entire US you probably need to dive everywhere in the US.
Ok sorry, I should have added "In general". Guided dives are not nearly as common in the US as they are in many other places. I dive never had a guided dive in the US, and I do quite a bit of diving. Sorry to ruffle your feathers.
