Re: Any USA-based photo workshops?
I don't know any, but since you mention Roatan...
I go to Roatan once a year, usually. Last week in September and then first week in October. I go in September because it's the off season at the place I go (Reef House Resort) and I am usually the only guest at the resort and on the dive boat. Nice having your own divemaster...
I've gotten pretty experienced at stills shooting underwater, and should your daughter be there while I'm there, I'd be happy to spend the evenings going over and post-processing shots with her. (I use Lightroom). It's not a workshop, and I'm not a photo instructor, just experienced. I've also been a martial arts instructor for many years and have some knowledge of teaching students in general.)
Here are images for previous Roatan trips:
In 2016 I finally got a housing for my DSLR and moved on from point-n-shoots.

In 2019 I upgraded from D810 to D850, and I went twice, one week in March, two more in September/October.

Some questions for you about your daughter.
1. How good a diver is she?
2. How much does she already know about photography and the camera she is going to use?
3. How much does she already know about post-processing?
4. Is she more interested in stills, video or both?
My experience has been that you need to be a pretty good diver to safely hold the camera steady in the spot it needs to be, and you absolutely need to know how to post-process.
Bluewater Photo (where I bought most of my gear) offers various photography workshops around the world with better instruction than I could offer for sure.
