Questions

Is there a KiCad symbol and footprint for the LM109K?

Yes. The symbol is EasyEDA_Cloud:LM109K and the footprint EasyEDA_Cloud:TO-3_L40.0-W26.7-P11.00-TL, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the LM109K?

TO-3-2, with 4 pins. Its footprint is drawn on this page.

Where is the LM109K datasheet?

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

Where can I order the LM109K?

JLCPCB lists it as part C3744698, with 0 in stock; the sellers' links on this page open their listings.

What can replace the LM109K?

Parts like it in the library: the XC6209B50APR-G by Torex Semiconductor, the XC6209F50APR-G by Torex Semiconductor, the XC6209B50ADR-G by Torex Semiconductor and the XC6209F50ADR-G by Torex Semiconductor. Check their datasheets: a part that fits the footprint may still differ in its ratings.
