Questions

Is there a KiCad symbol and footprint for the TL3844BD?

Yes. The symbol is EasyEDA_Cloud:TL3845BDR and the footprint Package_SO:SOIC-14_3.9x8.7mm_P1.27mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the TL3844BD?

SOIC-14, with 14 pins. Its footprint is drawn on this page.

Where is the TL3844BD datasheet?

Texas Instruments publishes it: the Datasheet link on this page opens it.

Where can I order the TL3844BD?

JLCPCB lists it as part C485109, with 100 in stock; the sellers' links on this page open their listings.

What can replace the TL3844BD?

Parts like it in the library: the UC2843ADTR by Texas Instruments, the UC2844BD by onsemi, the UC3843DTR by Texas Instruments and the TL2843BQDRQ1 by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.
