So none of the numerous blackholes in our galaxy have astrophysical jets? Seems unlikely, maybe small, thin, and/or far enough not to be observed, but that doesn't mean they aren't there.
Generally they're associated with quasars and formedby supermassive black holes at the centers of active galaxies, which our galaxy doesn't really qualify for. However, while relatively quiet, Sagittarius A* does accelerate things to fairly high speeds, and it is thought that it might have some faint jets and an accretion disk.
