Very interesting! Venus's atmosphere is so dense that it would take large sized and cohesive asteroidal bodies to penetrate to the surface with sufficient energy to blast surface rocks high up into the Venusian atmosphere. That may have happened in the distant past when such large collisions were more frequent, but is not so likely to have happened recently. So if that was the source of the phosphine, it would need to have a very long lifetime in the Venusian atmosphere. I'm no chemist, so I can't comment on that. Of course, asteroidal bodies have a greater velocity at the distance of Venus from the Sun, than at Earth's distance, but conversely there are fewer of them, and as already noted, the thick atmosphere is another contra-factor.

Venus Phosphine contribution to Earth's unusually high phosphorous levels, perhaps contributed to Earth's rapid rise in lifeforms. This may be time stamped by the Venusian thermal runaway apocalypse. As Venusian weak magnetosphere is of Solar Wind interaction. The lighter gas being stripped away and pushed to Earth's Solar radius.
