No, there are CD rips of TFA and TLJ available.
Were those uploaded online officially? I am aware that there were CD releases for those FYC soundtracks, but I was specifically referring to the files uploaded on https://disneystudiosawards.com that people were able to download, which were all uploaded in the mp3 format as far as I was able to find. That aside though, I think you’re right that there aren’t any lossless versions for TROS that have been made available, although I didn’t look too far into it.
