Questions

Is there a KiCad symbol and footprint for the LM317?

Yes. the footprint Package_TO_SOT_SMD:SOT-223, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the LM317?

SOT-223, with 4 pins. Its footprint is drawn on this page.

Where is the LM317 datasheet?

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

Where can I order the LM317?

JLCPCB lists it as part C22399960, with 210 in stock; the sellers' links on this page open their listings.

What can replace the LM317?

Parts like it in the library: the GM317AEMP by GREENMICRO, the FZT749 by Diodes Incorporated, the LM317G by GOODWORK and the LM317AG-JSM by JSMSEMI. Check their datasheets: a part that fits the footprint may still differ in its ratings.
