Questions

Is there a KiCad symbol and footprint for the BL3H7B?

Yes. The symbol is EasyEDA_Cloud:BL3H7B and the footprint Package_SO:SSOP-4_4.4x2.6mm_P1.27mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the BL3H7B?

SSOP-4, with 4 pins. Its footprint is drawn on this page.

Where is the BL3H7B datasheet?

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

Where can I order the BL3H7B?

JLCPCB lists it as part C41425718, with 2,604 in stock; the sellers' links on this page open their listings.

What can replace the BL3H7B?

Parts like it in the library: the AT3H4B-CUH-S by AOTE, the HT-3H4-BTP1 by HENGTUO ELECTRONICS, the LTV-214B by AOTE and the MP3H4B(T1)-GV by miracle. Check their datasheets: a part that fits the footprint may still differ in its ratings.
