Questions

Is there a KiCad symbol and footprint for the LBAT54HT1G?

Yes. The symbol is Device:D_Schottky and the footprint Diode_SMD:D_SOD-323, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the LBAT54HT1G?

SOD-323, with 2 pins. Its footprint is drawn on this page.

Where is the LBAT54HT1G datasheet?

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

Where can I order the LBAT54HT1G?

JLCPCB lists it as part C12744, with 128,917 in stock; the sellers' links on this page open their listings.

What can replace the LBAT54HT1G?

Parts like it in the library: the 1N5819WS by Guangdong Hottech, the B5819WS by hongjiacheng, the 1N5819WS S4 by JSMSEMI and the CUS10S30,H3F by Toshiba. Check their datasheets: a part that fits the footprint may still differ in its ratings.
