Quick question - how is the create NFO process actually triggered in scenarios where it is missing? I have noticed NFOs created for episodes that I’ve watched, but it doesn’t seem to operate for new additions to the library that I’ve not yet watched. Do I need to watch each episode for the NFO creation process to be triggered, or is there another way?

To create the missing .nfo's you can do a Library Backup.
Settings > Media > Export Library
Backup to separate files. Follow the prompts and Kodi will save each TV, Movie, MTV etc's data to an .nfo file, plus backup all your artwork etc.
Hope that helps.
