Tyler Robinson's grandparents recorded saying he was framed

Which part? A reporter talked to Tyler Robinson's grandparents on a break at a courthouse and they agreed with her that Robinson is a patsy for Charlie Kirk's murder. If you want the evidence that he was framed, it's too much to type and other people have broken it down better than I could.

I thought the theory was that he took the shot but Jews groomed him into doing it via discord trannies or something

No, that's the flimsy cover-up the DOJ threw together. The official story is simply impossible. The timeline doesn't add up and the gun doesn't line up with the wound. The "photos" they used to identify him were AI-enhanced, i.e. fabricated. The DOJ and corporate media have been caught in many, many inconsistencies and have been covering the story as if he's already known to be guilty, which is odd in itself. ABC also modified footage of at least one of his court dates to make it look like he reacted differently to the questions he was asked. It's 100% a frame job. Those are just a few factors, not all of them.

Who actually killed him then? Mossad second shooter?

I don't know. A lot of people think CK's security team, or at least its head Brian Harpole, was involved. Some people at TPUSA – especially Erika Kirk, Andrew Kolvet, and Blake Neff – have been acting suspiciously in that they're desperate to shut down all discussion about the official narrative being a lie. That's extremely telling IMO. I don't know if the DOJ knows what really happened.

Why not both
