Questions

Is there a KiCad symbol and footprint for the FS4803?

Yes. The symbol is EasyEDA_Cloud:APM4953 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 FS4803?

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

Where is the FS4803 datasheet?

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

Where can I order the FS4803?

JLCPCB lists it as part C5441155, with 2,724 in stock; the sellers' links on this page open their listings.

What can replace the FS4803?

Parts like it in the library: the AP4435C by ALLPOWER, the AO4407A by UMW, the AO4468 by JSMSEMI and the AO4435 by UMW. Check their datasheets: a part that fits the footprint may still differ in its ratings.
