You can probably implement your own these days. I would use a model to generate a requirement document, then human review, then generate an implementation plan, then human review, then take it to build. Have a different model to a code review and testing. End with human code review and testing.
You could make your own BitLocker conforming to your requirements without relying on or trusting any cloud or corporate entity.
And then turn Mythos onto your code to make sure you don’t have vulnerabilities? That’s a lot of faith in the security of LLM-written code that I wouldn’t have in human-written code.
The point is the code is there in front of you. You can audit it, study it, turn mod and after model loose on it, do whatever you want. You’re going to have to compile it so you need to trust the compiler but at least it’s not some cloud provider.

I mean it's better than this sdcard thing at least.
