Questions

Is there a KiCad symbol and footprint for the BL3401?

Yes. the footprint Package_TO_SOT_SMD:SOT-23, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the BL3401?

SOT-23, with 3 pins. Its footprint is drawn on this page.

Where is the BL3401 datasheet?

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

Where can I order the BL3401?

JLCPCB lists it as part C5350180, with 3,006 in stock; the sellers' links on this page open their listings.

What can replace the BL3401?

Parts like it in the library: the SI2318 by GOODWORK, the 6P03 by GOODWORK, the AO3400AL by TECH PUBLIC and the AP3401BI by A Power microelectronics. Check their datasheets: a part that fits the footprint may still differ in its ratings.
