LEGO Star Wars: The Skywalker Saga

For me this was easily done on episode 1 - now this is pod racing(the last level). While shooting ships and satellite dishes simply fly through any rings of studs you can find and after quite a few of them true jedi will be achieved and it will pop.

Episode 2 level 1 is also a good option for this, especially if you shoot the purple towers

In each mission there are 3 sections to fill by picking up studs. Fill the end of the purple one to unlock this True Jedi. In Star Wars a New Hope (If you are old school and wanna play 1979 first and work your way chrono through it) then this will be done before you even start to take control of R2D2 and C3PO
Just remember to look out on the walls for destructible scenery and just grind the hell out of this and remember that studs don't always collect right when you walk over them and also they vanish if you are not quick enough to get them.
