There is quite literally no evidence for this theory and mountains of evidence that USB-C is what they were always going to switch to. They had already switched checks note almost every other device they make to USB-C. The few that weren't USB-C at the launch of the iPhone 15 have been moved since then (specifically keyboard and mouse). I'm not sure if there are any Lightning devices left at this point.
