Let's see... according to Ubiquiti's web page, it seems that "LiteAP AC" is a family of devices with two members: LAP-120 and LAP-GPS.
The LAP-120 was previously called LiteBeam 5AC 16 120 (LBE-5AC-16-120), but then it was renamed. Still there are some references on the website (https://dl.ubnt.com/datasheets/LiteBeam/LiteBeam_DS.pdf), where you can see it has exactly the same characteristics. I believe the hwdata pages should be merged, and explain this on device page.
The LAP-GPS appeared later, and it doesn't have any entry in the ToH.
Regarding the devicepages, I don't know whether it makes sense to have LAP-120 and LAP-GPS (whenever it is added) in two different pages, or have a common one for the LiteAP AC family (e.g.: https://openwrt.org/toh/ubiquiti/powerbeam_5ac). You probably have more criteria than me.
I'm not opposed to having LAP-120 and LAP-GPS on the same page, IF they are similar enough (e.g. same SoC, same installation instructions, ...). If they are completely different animals in terms of hardware and installation, I'd put them on separate pages.
They are both WA-type Ubiquiti devices, same SoC and installation procedure, similar shape, dimensions, antenna pattern and intended use. One has an additional 2.4 GHz management radio and GPS, the other does not.
I think it makes sense to have a single devicepage for them and two hwdata pages, one each.
