Questions

Is there a KiCad symbol and footprint for the LM317?

Yes. The symbol is EasyEDA_Cloud:AIC1117AGYTR and 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?

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

Where can I order the LM317?

JLCPCB lists it as part C22466422, with 10,413 in stock; the sellers' links on this page open their listings.

What can replace the LM317?

Parts like it in the library: the LM317G by UMW, the LM317DCYR by UMW, the TL1963A-33DCY by Texas Instruments and the BL8071GCLATR33 by BL. Check their datasheets: a part that fits the footprint may still differ in its ratings.
