Some people here and elsewhere wonder if Luthien might be a former Jedi (or even Sith). It's possible, but here is my reasoning why within Andor's more "grounded" feeling it would be wrong:
The time for Jedi to save the day comes later, after the ordinary people have done the basics. The Rebellion's foundation and growth must be based on the expressed will of the oppressed, the victims of the Empire starting to resist, not the whims of a superpowered individual. Only then does the legitimacy exist for what is basically a superhero to help them accomplish their goal. It's already the will of the people for the Empire to end, they just can't do it alone because the Empire is lead by a supervillain, too.
If the Jedi basically manipulate the Rebellion into existence, it loses legitimacy. Of course, some would point out that it's a symmetry, a Sith manipulated the Empire into existence, a Jedi manipulates the Rebellion to defeat it. But I think it violates the spirit of the Jedi being the good guys. The Sith do things because they want to serve their own interests, the Jedi do things to serve the interests of the people. For a correct symmetry, the Rebellion has to be started and organized by "ordinary" folk.
I could be wrong, of course, then you can all laugh and point.
