Does Eurocontrol ever check for a VFR leg passing through airspace where VFR is banned?

Eurontrol doesn’t proceed any VFR leg.

And an IFR FPL that validates doesn’t mean you can actually fly it.
You can file an IFR FPL with a load of DCT and end-up in a P area. We already discussed that somewhere else.

VFR is outside the scope of Eurocontrol. So they don’t care.

But the profiler does look into the VFR portion, so you can get unrealistic descent profiles (and even plan rejections) because it doesn’t account for traffic circuits, for example.
