I also wish GM wouldn't make the front fogs have to be switched on every time instead of just staying in the selected on/off position after a key cycle. My Camaro does the same thing- I have to switch them on every single time.
Why do you need the fog lights on all the time? Is it always foggy when you're driving?

I use the fog lights for extra visibility for myself and also for the surrounding cars to see me when the headlights are necessary.
The car has auto headlights and DRLs. You are needlessly dazzling other drivers by having your fog lights on in clear weather. I have also yet to see a fog light implementation that actually improved my visibility in fog, they all just illuminate more of the fog in my experience.

A word of caution about switching to LED backup lights. I tried that on my 2008 Dodge Magnum. It looked great. Even from the drivers seat, you could see a large glow of pure white light emanating from the back of the car. Problem was, even though it was bright, it didn’t project rearwards. You couldn’t see enough in the direction you were backing up to. After a year, I switched back to the regular bulbs and the improvement was noticeable. You might have better luck with the TourX, but don’t get fooled by brightness, it’s the rear projection which matters most.

The layout of the LED'S will be how well they will project. Unfortunately all LED'S are not the same as with regular filiment lamps, so the one size fits all doesn't apply. Understanding the difference between Kelvin and Lumens will also help in making a difference in picking the correct LED. Kelvin and Lumens are two different measurements and do not always mean the type of brightness output.

Hate to disagree, but it’s not that easy. The model is too new. Everything hits pre-2017 Insignia cars.

I’ve tried nearly every European market for diagrams and it’s scarce.

I also have done rear fog upgrades in Volkswagens. At least with them you can use ETKA to reference anything you want.
Great--didn't realize that the tail lights are different, so two more items to put on my shopping list.
Regal left & right tail lights are 39125834 and 39125833, Insignia (L & R) are 39125835 and 39125832.
