Are there available rifling buttons for these platforms? I can't find them anywhere. Even hammerbutton does not have them. Or is there some rifling button with specific characteristics that work, but they are not specifically labelled as AR15/M4?

How do you do rifling at home? Is it that electrolysis thing I see? Or something more forceful?

A rifling button is basically a machine tool that gets pushed through the barrel forcefully using a hydraulic press to cut the rifling into it.

On the other hand, the ECM (electrochemical machining) method is completely different and has its own benefits/drawbacks. It's great if you don't have access to buttons or presses, but you do have a 3D printer.
