Seems like the answer is yes because this is how they’re making it - is it more efficient to generate power with one giant turbine vs a bunch of smaller turbines of equivalent volume?
Yes, it is. Because the area of wind that a turbine can capture is pi*r^2, (where r is the length of the blades), the area increases with the square of the blade length. So doubling blade length gives you four times the wind area.

I suspect it’s certainly cheaper overall.
Building at sea isn’t cheap, even in shallower waters. Fewer big foundations is going to be easier than many smaller ones.
