Generative Fill

Does Lightroom do Generative Fill? Not Generative Erase, but Generative Fill.

Often when I rotate an image I want to keep all of it and if the rotation is not too large I try to fill in the information missing due to the rotation.  I used to do this using clone tools but thought that it would be a lot easier using Generative Fill. Just rotate the image, fill in the black areas generated by the rotate and save the image.

But I have run into problems trying to do this in Lightroom, both LR and LRC, both of which I am currently trial-ing. I rotate the image to fix the horizon but can not find any way to crop outside of the actual image so I lose the corners. But even if I could keep the dead areas I could not find any Generative Fill in either LR or LRC. Is it there and I am just missing it? So I guess I am asking two questions. Can I crop outside of the actual image? And is there some way to do Generative Fill in any resulting part of the image.

I am working on a Silicon MacBook Air running Sequoia.
