There are more than enough good fonts under OFL that it surprises me people want to commission a custom font primarily for licensing reasons rather than using a standard one.
A brand is still free to commission a copy/clone of an 'interesting' font that has character (or, beware even serifs) ...
If you produced a bunch of screenshots of the output at various sizes, and then asked an LLM to convert to ttf or whatever, I’m guessing that’d be OK. I’m not an expert in this stuff though.
