Don’t suppose there’s a Linux phone?

Linux phones have considerable problems unfortunately. The biggest being battery life, which is a problem with Linux in general. The other major hurdle is getting certain apps to work, banking apps being the biggest difficulty. If what you're really looking for is a phone that you have much more control over, I would suggest an alternative android-based OS. I was in a similar position as you, looking for a phone I could control and trust, and I ultimately landed with a Pixel phone with GrapheneOS, which I have been immensely happy with and it gave me pretty much everything I was looking for in a Linux phone. GrapheneOS is only developed for the Pixel series of phones though, so if you're looking at different models (or have a non-Pixel already), then you'll need a different OS. There's been some good threads about it on here if you search around.
