But your pressure difference from the surface to the deep deep is 1
atmosphere per 33'. From sea level to space, it's just 1 atmosphere
pressure difference.

If you can grow a structure that can handle hundreds to thousands of
pounds per square inch pressure, then you can cognitively grow one
that'll handle zero pressure by being dead/rigid tissue from the start.
And if the tissue gets cracked to the living part, the living part would
be organically inclined to emit a mucus that hardens when exposed to
vacuum as an instant damage control function. I'm handwaving here, but
then so is the whole idea of large thinking bio constructs in the first
place.
