Some modern windsurfboards are hollow with nomex/foam sandwich and carbon around the outside providing stiffness.
The sandwich structure (foam/nomex) + inner layer carbon has tp be lighter than the foam you would normally have in a board.
Can imagine there's a certain board size where this hollow build method starts to gain weight advantages, but for a small kitefoil board I'd doubt there is a benefit in weight, let alone the manufacturing complexety

Super-boyancy can be achieved by simply changing the liquid medium you´re carrying out your sport on/in.
Exchange water with mercury. 19-times higher boyancy with the same board! Great stuff!

I split the difference on my 13 lb, 150 liter wingboard. “Hollow” but no inner carbon, just 1inch foam “honeycomb”. I did a lot of calculations and you only save a lb or so going hollow with inner carbon layer until in the 100+ liter range where the weight savings really adds up, but the expense does too!!

Wow, love the concept!.And that weight is amazing for that volume.
"She ain't exactly pretty,she ain't exactly small..." as Bon Scott said
but she looks like a total magic carpet ride.
I am planning a wingfoil board construction (first one) and i keep running the hollow nose ideas around my head but as you say,for below 100l the weight gain is probably marginal.I might still do some hollowing because a single gram loss way in front is going to add a bit of liveliness.
The windsurf boards you are talking about are probably Patrik's Air Inside tech , he is getting into wingfoiling too.

Interesting!
Another good In-betweeen would be a chambered foam core, anyone done something like this?
