99% of 240v hot tubs have a regular breaker in the panel rated at 50-60a. that feeds a hot tub sub panel that contains a disconnect via a 50-60a GFCI that by code has to be near the tub. This is where the home owner kills the tub to do work on it like draining and refilling etc. It is also there for safety so the GFCI can be tested monthly and if the tub trips it or something goes wrong like a hose breaks you can quickly shut it off. It is not allowed to put the GFCI into the main panel and wire it all the way out to the tub. even though people do it.The 50a current rating wouldn't be a problem if fed by a properly sized breaker. I guess the only problem might be whether it's configured as a branch circuit or sub panel.
If someone removed the tub and saw the GFCI sub panel as a place to pull off 120v for some outlets all the overload protection backing it up would be too high. This I believe is what the OP thinks was done.
To the OP if you someday want a hot tub it would be great to have the GFCI sub panel already in place, but you don’t want it under the deck where it is hard to get at and not to code anyway. Depending on where the main panel is and what’s involved you could use this box as a junction box for a new tub and run out of it to a new one above the deck and at least 5’ from the tub.
