If I’m going for the grainy retro look for some lowlight photos would it make sense to keep ISO low and add grain in post, or would the grain from turning up the ISO give a different kind of grainy look?

Depends what you’re trying to achieve.
CMOS noise, especially deep in the shadows, sort of clusters in strips. It can be a giveaway or just a slightly undersired look compared to “film” style grain which has some interesting properties on it’s own but is easy to simulate at useful scales.
Shoot to get the picture. If going higher ISO doesn’t hurt your result and makes it easier to get the shot, then go for it.
Careful when adding noise though - I tend to avoid it because it’s not “truthful”, but we’re all just making pictures here. It may not make sense when looking back after a few years
