You’re mixing things up. There are commercial toroidal propellers for boats, they have been in production for years, but cost $5000 each.

MIT recently developed toroidal propellers that they demonstrated with a quad rotor drone. No reason they couldn’t be scaled up to fit this. But the question is will they, not can they.

I thought they weren’t really produced until a couple years ago.

Also apparently MIT (of course) is already trying them on air-based drones: https://newatlas.com/aircraft/toroidal-quiet-propellers/
