Questions

Is there a KiCad symbol and footprint for the BL78L33?

Yes. The symbol is EasyEDA_Cloud:BL78L33 and 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 BL78L33?

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

Where is the BL78L33 datasheet?

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

Where can I order the BL78L33?

JLCPCB lists it as part C21882683, with 438 in stock; the sellers' links on this page open their listings.

What can replace the BL78L33?

Parts like it in the library: the JTD7533H by JTD, the AZ1117R-3.3TRE1 by Diodes Incorporated, the AMS1117-3.3OF by GREENMICRO and the HR71L33V by hongjiacheng. Check their datasheets: a part that fits the footprint may still differ in its ratings.
