Interesting! I found https://www.orlando-international-airport.com/ https://www.orlando-international-airport.com/, which only mentions car rental and undefined "Airport Shuttles"/"Hotel Shuttles"/"Taxis & Limos", and they did not show up on Google Maps. That's indeed quite a lot more. The Lynx buses at 30/60-minute intervals seem quite usable for most purposes, too bad they don't have a convenient transfer from the train.
