Not yet, as far as I know. But creating a basic Pascal header, that wraps what is exposed inside Bullet-C-Api.h, should be trivial. And once you have this, you can translate to Pascal a Bullet demo like BulletDinoDemo. And then you have working Bullet with rigid body , which you can start to integrate with Castle Game Engine.

(The next step is to extend Bullet-C-Api.h to add there soft body and other stuff, and then translate that to Pascal too. Currently Buller C header doesn't include the full Bullet API (that is only in Bullet C++ object-oriented API), but Bullet developers have stated many times that they welcome contributions there.)
