This is mostly just an issue with TROS since there was never any indication in the previous films that Leia had been trained as a Jedi, other than the space walk in TLJ and even that’s a stretch.

It would be an interesting angle if Leia’s decision was portrayed as a failure, but this is supposed to be a hopeful scene, “Leia failed the galaxy and doomed us all by choosing a career in politics” doesn’t fit a scene that is supposed to restore Rey’s spirit. To be fair neither does a premonition of death but that’s why we removed that bit.
