Questions

Is there a KiCad symbol and footprint for the 78L09?

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 78L09?

SOT-89-3, with 5 pins. Its footprint is drawn on this page.

Where is the 78L09 datasheet?

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

Where can I order the 78L09?

JLCPCB lists it as part C22458782, with 6,741 in stock; the sellers' links on this page open their listings.

What can replace the 78L09?

Parts like it in the library: the LR78L09A by Leshan Radio (LRC), the 78L09-150 by UMW, the 78L09 by HXY MOSFET and the 78L09T by Foshan Blue Rocket Elec. Check their datasheets: a part that fits the footprint may still differ in its ratings.
