It's certainly possible to create a PWA with React, Inertia & Laravel. If you can't find a RILT PWA tutorial, then one that covers React should work as it's the client-side code that's key to PWA classification. Any updates to the Laravel server-side code will be the same as are covered in the tutorials you mention.
If there are particular aspects of the PWA classification you're struggling to implement then I would try searching for tutorials/examples of those particular aspects.
