You can extrapolate and make some reasonable guesses. Find out times they use for a few traditional emulsion films they do, and look up the times those films have with XTOL at a different dilution or temperature. Find out how much your film's times vary with that same dilution and temperature, and make an educated guess as to how it might vary with your lab's procedure.
I'd tell you that developing film at home is easy and doesn't even require a darkroom, and will save you money if you do enough film, but apparently you don't want to hear it. So consider this advice to be for anyone else who reads this thread in the future.
