Questions

Is there a KiCad symbol and footprint for the LM317HVT?

Yes. The symbol is Regulators:REG3+1 1ADJ-2OUT-3IN+4OUT and the footprint ICs And Semiconductors THD:TO-220-H, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the LM317HVT?

TO-220, with 4 pins. Its footprint is drawn on this page.

Where is the LM317HVT datasheet?

Texas Instruments publishes it: the Datasheet link on this page opens it.

Where can I order the LM317HVT?

JLCPCB lists it as part C468256, with 1,867 in stock; the sellers' links on this page open their listings.

What can replace the LM317HVT?

Parts like it in the library: the LM7905CT by Texas Instruments, the LM317AT by Texas Instruments, the LM317AT by HGSEMI and the LM7912CT by HGSEMI. Check their datasheets: a part that fits the footprint may still differ in its ratings.
