Questions

Is there a KiCad symbol and footprint for the KA3843?

Yes. the footprint Package_SO:SOP-8_3.76x4.96mm_P1.27mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the KA3843?

SOP-8, with 8 pins. Its footprint is drawn on this page.

Where is the KA3843 datasheet?

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

Where can I order the KA3843?

JLCPCB lists it as part C18185156, with 2,181 in stock; the sellers' links on this page open their listings.

What can replace the KA3843?

Parts like it in the library: the UC3843-HXY by HXY MOSFET, the UC3845-HXY by HXY MOSFET, the CLR6204SQA by ChipLink Tech and the CR3005 by Chip-Rail. Check their datasheets: a part that fits the footprint may still differ in its ratings.
