1 year ago RadioLib already supports ASR650x series in the CubeCell modules made by Heltec: https://heltec.org/project/htcc-ab01-v2/ The biggest hurdle to overcome there was their ... let's say questionable Arduino core.
That same Arduino core (https://github.com/HelTecAutomation/CubeCell-Arduino) also supports the ASR660x series, so it should already work - however, this only applies to running the code directly on the SoC.
For the board you linked, I'm not sure if that is an option since it seems the code on the SoC is fixed and you can only feed it AT commands from a higher system (such as a PC or a different microcontroller via the UART interface). RadioLib doesn't support that mode of operation, since the AT interfaces are typically quite limited in functionality compared to direct SPI access.
However, if you don't require ASR660x, you could use the Heltec board linked above. It has a different SoC (ASR6501), but it seems to be working like any other Arduino-type devboard. I have no personal experience with either option.

Pardon me for my lack of knowledge in this field. I am a beginner just starting experimentation with LoRa, I stumbled across this module by Dragino named LA66 viewable below.
I was particularly interested in their USB Devboard which is essentially the previously mentioned LA66 module with an integrated CP2102 USB to TTL and other devboard nice-to-haves.
The LA66's source files, drivers and more are viewable here and here
Digging a bit further, I found their FCC listing which included extra info. These listings can be viewed on fcc.gov or fccid.io or on archive.org. The main item which peaked my interest was the internal photos which showed this module utilises the ASR6601SE SoC from ASR Microelectronics. A datasheet for this product can be found here and here A brief excerpt is repeated below:
A hackster.io article featured this SoC.
I believe this module/SoC is quite powerful, outputting +22 dBm means it is in the higher bracket AFAIK when it comes to LoRa Transceivers and has quite excellent(ish) documentation from the manufacturers'. The only issue I forsee is control over the SoC as it appears to be controlled via AT commands, possibily enforcing restriction upon what may be TX/RX.

If any links die I have backups I can make available upon request for most documents
Finally on a more personal note (I apologise if this section is a bit far offtopic); Would this be a decent begginner board? I have a bit of experience in RF and think I could probably contribute to integrating this into this project, or should I go with the standard SX12XX modules which have been embraced by the OSS community? My plan is to (attempt to) contribute meaningfully with whichever board I ultimately decide. (Unfortunately I'm a dumbass who happens to have an internet connection so no guarantees)
