Otis used rectifer tubes on its touch buttons. They used tubes in other controllers, but there were no vacuum tube controllers. Otis did have an op-amp dispatch controller. Turnbull had a vacuum tube motor control on a wound brake to force a three phase AC motor to slow down to a smooth stop. Tubes have been used in timer circuits and other peripheral equipment.
I'm not exactly sure what you mean by "op-amp dispatch controller"?
I think dispatch controller means the controller used on a bank of multiple elevators that decides which elevator can answer a hall call the fastest.
I assume you are talking about vacuum tube op-amps.
Is the dispatcher mostly relay logic with a few vacuum tube op-amps for specific functions? Or are the vacuum tubes used for most of the dispatcher logic and there are few relays?
