Same I've used shimano/sram jagwire with campy and it's been fine.
I've also emailed Jagwire and have never heard back from them. Glad it's not just me.
I have a sealed shift kit--which is basically just full-length cable liners--on my gravel bike because otherwise the cables start squeaking after about 0.38 seconds on dusty gravel. But I also have Campy Potenza on that bike and Jagwire doesn't make a Campy-specific sealed shift kit.
So I just buy the sealed shift kit and buy Campy cables separately. It all works swimmingly.
