Questions

Is there a KiCad symbol and footprint for the LR78L05?

Yes. The symbol is Pinmap_Generic:Regulator_Linear_1OUT_2GND_3IN 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 LR78L05?

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

Where is the LR78L05 datasheet?

Leshan Radio (LRC) publishes it: the Datasheet link on this page opens it.

Where can I order the LR78L05?

JLCPCB lists it as part C95669, with 0 in stock; the sellers' links on this page open their listings.

What can replace the LR78L05?

Parts like it in the library: the MC79L05ACPG by onsemi, the L78L05ACZ by STMicroelectronics, the L78L05ABZ by STMicroelectronics and the LM79L05 by HTC. Check their datasheets: a part that fits the footprint may still differ in its ratings.
