Questions

Is there a KiCad symbol and footprint for the LM317G-AA3-R?

Yes. The symbol is EasyEDA_Cloud:LM317_C5296732 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 LM317G-AA3-R?

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

Where is the LM317G-AA3-R datasheet?

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

Where can I order the LM317G-AA3-R?

JLCPCB lists it as part C19651, with 9,617 in stock; the sellers' links on this page open their listings.

What can replace the LM317G-AA3-R?

Parts like it in the library: the NCP1117ST33 by onsemi, the AZ1117H-3.3TRE1 by Diodes Incorporated, the LD1117AG-33-AA3-A-R by UTC and the AZ1117CH-3.3TRG1 by Diodes Incorporated. Check their datasheets: a part that fits the footprint may still differ in its ratings.
