According to the linked defect, later builds - oreo and pie - were made but they had a bug that made the phone unusable. Nothing in the defect report indicates that the problem has been fixed, and no clear indication (in my reading) that the torch app is to blame. So any new build is likely to have the same problem.
I don’t have the ability or knowledge to make a build without certain apps - I just run Docker, and if the builds work, then great. If they don’t, then there’s not a lot I can do.
Also, I don’t have any plans to make more builds any time soon. If I do, they will likely be for Sony devices currently limited to Nougat builds.
In short, I’m sorry, but I don’t think I can help
