Questions

Is there a KiCad symbol and footprint for the LM317?

Yes. the footprint Package_TO_SOT_SMD:SOT-89-3, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the LM317?

SOT-89, with 3 pins. Its footprint is drawn on this page.

Where is the LM317 datasheet?

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

Where can I order the LM317?

JLCPCB lists it as part C41382584, with 12 in stock; the sellers' links on this page open their listings.

What can replace the LM317?

Parts like it in the library: the AMS1117-3.3S by UMW, the AS78L05RTR-E1 by Diodes Incorporated, the HT7550-1 by UMW and the L78L33ACU by STMicroelectronics. Check their datasheets: a part that fits the footprint may still differ in its ratings.
