Questions

Is there a KiCad symbol and footprint for the 78L33?

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 78L33?

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

Where is the 78L33 datasheet?

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

Where can I order the 78L33?

JLCPCB lists it as part C46061585, with 6,733 in stock; the sellers' links on this page open their listings.

What can replace the 78L33?

Parts like it in the library: the AMS1117-3.3S by UMW, the AMS1117-3.3 by GOODWORK, the CJA1117B-3.3 by Jiangsu Changjing Electronics Technology (CJ) and the AZ1117CR-3.3TRG1 by Diodes Incorporated. Check their datasheets: a part that fits the footprint may still differ in its ratings.
