I get the same exception on both Intel and Arm when I try to import sage.all from the sage python. There is no exception if I do the same import in sage -python. But that is no help in terms of running lldb. However, perhaps if I knew how to set up the correct environment first I would be able to start the sage python in lldb and then actually be able to do the import.
