The OnePlus 3T seems to be officially supported by LineageOS[1].
I'd actually trust my phone more (using the official LineageOS build) as basic system components are FOSS (although there are some firmware blobs).

Yes, but everything I have read, anybody who tried only the official ROM had various problems, e.g. with the camera. Hence I settled on an unofficial ROM.
But even if I used the official ROM, there is absolutely nothing on the LineageOS website that makes me trust them. No real names, no GPG keys, nothing. Just "The LineageOS project", a bunch of pseudonyms in the blog entries and apparently some LLC. Even their "Legal" sub-page does not contain anything at all.
