Questions

Is there a KiCad symbol and footprint for the WS2818B?

Yes. The symbol is EasyEDA_Cloud:WS2818M and 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 WS2818B?

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

Where is the WS2818B datasheet?

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

Where can I order the WS2818B?

JLCPCB lists it as part C114582, with 4,259 in stock; the sellers' links on this page open their listings.

What can replace the WS2818B?

Parts like it in the library: the AD8240YRMZ by Analog Devices, the WS2814 by Worldsemi, the USVI-060012FG by Delta Elec and the RL12-60M-LED-277 by Hatch Lighting. Check their datasheets: a part that fits the footprint may still differ in its ratings.
