My guess is that you are stretching the limits of your machine. Based on the specs you gave, it looks like you are working on a MacBook Pro 15" 2017 model. If so, you should have enough processing power with your i7 to run Ableton Live, which can run on an i5.
That said, Ableton is a seriously CPU intensive application, and you are running Ventura on the earliest model machine that it is available for (that is, Ventura will not run on a MacBook older than the 2017 models).
Given this, it is likely that, as you suggested, you are testing your machine's outer limits by running OS 13 Ventura and Ableton Live. When I ran Ableton on my 2016 MacBook Pro, it would get mighty hot, and that was with a far earlier version of MacOS (OSX either High Sierra or Mojave, can't remember which anymore). It never fully overheated, but it would be uncomfortably hot.
