Questions

Is there a KiCad symbol and footprint for the LM317?

Yes. The symbol is EasyEDA_Cloud:CBM317DT and the footprint EasyEDA_Cloud:TO-220-3_L9.9-W4.5-P2.54-L-1, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the LM317?

TO-220, with 3 pins. Its footprint is drawn on this page.

Where is the LM317 datasheet?

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

Where can I order the LM317?

JLCPCB lists it as part C7463411, with 89 in stock; the sellers' links on this page open their listings.

What can replace the LM317?

Parts like it in the library: the L7818CV(MS) by MSKSEMI, the KA337TU by onsemi and the LD1086V18 by STMicroelectronics. Check their datasheets: a part that fits the footprint may still differ in its ratings.
