Questions

Is there a KiCad symbol and footprint for the LM317LZ?

Yes. The symbol is Celestial_Power_Linear_VReg:TI LM317L and the footprint EasyEDA_Cloud:TO-92-3_L4.9-W3.7-P1.27-L, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the LM317LZ?

TO-92-3, with 3 pins. Its footprint is drawn on this page.

Where is the LM317LZ datasheet?

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

Where can I order the LM317LZ?

JLCPCB lists it as part C5267874, with 2,330 in stock; the sellers' links on this page open their listings.

What can replace the LM317LZ?

Parts like it in the library: the MC79L05ACPG by onsemi, the L78L05ACZ by STMicroelectronics, the L78L33ACZ by STMicroelectronics and the LM79L12 by HTC Korea TAEJIN Tech. Check their datasheets: a part that fits the footprint may still differ in its ratings.
