Questions

Is there a KiCad symbol and footprint for the LM317D2T?

Yes. The symbol is Regulators:REG3 1ADJ-2IN-3OUT and the footprint Package_TO_SOT_SMD:TO-263-2, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the LM317D2T?

TO-263-2, with 3 pins. Its footprint is drawn on this page.

Where is the LM317D2T datasheet?

onsemi publishes it: the Datasheet link on this page opens it.

Where can I order the LM317D2T?

JLCPCB lists it as part C12848, with 16,244 in stock; the sellers' links on this page open their listings.

What can replace the LM317D2T?

Parts like it in the library: the L7805ABD2T-TR by STMicroelectronics, the CJ7812 by Jiangsu Changjing Electronics Technology (CJ), the CJ7805 by Jiangsu Changjing Electronics Technology (CJ) and the L7808ABD2T-TR by STMicroelectronics. Check their datasheets: a part that fits the footprint may still differ in its ratings.

Which open-source boards use the LM317D2T?

1 board in 1 repository on GitHub; the most starred are listed on this page, with their KiCad files.
