Why? In Tatooine Ghost the Jedi refused to accept her message.

A book published in 2003.

It's almost like the EU was filled to the brim with authors who either did not understand or did not like the Jedi philosophy and so actively took opportunities to write the Jedi as callous and calculating.

Considering we know for a fact that a number of Jedi retain connections to their homeworld, there is literally no evidence that the Jedi keep them separated their whole lives. Count Dooku is literally called that because he was allowed to keep his birth title.

It's also established that Padme, in canon, made attempts to help Shimi only a couple years after the Phantom Menace. She found her already freed and with the Lars family. So it is entirely likely that the Jedi knew Shmi was fine and that they assumed Anakin would simply reconnect with her after he was raised to the rank of knight.
