I don't think there is a good 120Hz touchscreen gaming laptop, which part would you be willing to compromise on ? I would recommend to let go of the touch screen since most gaming laptops don't have that feature. if it is an absolute must then you can use this on any gaming laptop you want.

disable the touchscreen
if it's running windows use https://custom-resolution-utility.en.lo4d.com/windows with a smaller res to avoid the failing corners

Although they're not often used today, the very old-school "infrared grid" touchscreens would work fine. You used to see them installed on the front of CRT monitors. They have a bunch of IR LEDs on two sides and IR sensors on the other two. When you touch the screen, you break the path between some of the LEDs and matching sensors, letting it determine the X/Y position of the touch event. They generally can't do multitouch or anything else fancy, and the only ones I ever saw were designed for POS use (esp. restaurant POS systems) and they emulated PS/2 mice as their connection to the host, usually. Now they might be hard to find, but ~10 years ago you could find them at surplus stores and the like, just by looking for POS-type CRTs with suspiciously thick bezels and extra cabling hanging off them.
You could probably DIY something that worked on the same principle pretty easily, particularly if you didn't care too much about high resolution (you wanted something for really big touch targets). Basically you'd just strobe the X and Y axis LEDs sequentially, while at the same time checking each corresponding sensor on the other side of the screen to see if it was 'seeing' the LED. I've seen a project that did this with LED strips for a "touch wall" but I can't find the build page right now.
If you don't want to roll your own, a few companies make COTS products which basically do something similar to the infrared grid touchscreens but with only a single bar (typically on the bottom of the screen). I'm not entirely clear how they work, except they must sense distance from the sensor array in order to get X/Y position. They're quite cheap. See this thing, for example. Can't vouch for one personally though.
Have you thought about using an Airbar so that the whole thing was touch too?
