Questions

Is there a KiCad symbol and footprint for the BL78L18?

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 BL78L18?

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

Where is the BL78L18 datasheet?

Galaxy Microelectronics publishes it: the Datasheet link on this page opens it.

Where can I order the BL78L18?

JLCPCB lists it as part C21882598, with 510 in stock; the sellers' links on this page open their listings.

What can replace the BL78L18?

Parts like it in the library: the 78L18U by TDD, the 78L18SI by YFW, the MCP1804-J002I/MB by Microchip Technology and the LM78L18F by HTC Korea TAEJIN Tech. Check their datasheets: a part that fits the footprint may still differ in its ratings.
