Is there a KiCad symbol and footprint for the PCA9574BS?

Yes. The symbol is EasyEDA_Cloud:PCA9574BS,118 and the footprint EasyEDA_Cloud:HVQFN-16_L3.0-W3.0-P0.50-BL-EP1.6, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the PCA9574BS?

HVQFN-16-EP(3x3), with 17 pins. Its footprint is drawn on this page.

Where is the PCA9574BS datasheet?

NXP Semiconductors publishes it: the Datasheet link on this page opens it.

Where can I order the PCA9574BS?

JLCPCB lists it as part C2652345, with 5 in stock; the sellers' links on this page open their listings.

What can replace the PCA9574BS?

Parts like it in the library: the PCA6408ABSHP by NXP Semiconductors, the PCA9554BBSHP by NXP Semiconductors, the PCA9555PW by NXP Semiconductors and the AW9523BTQR by AWINIC. Check their datasheets: a part that fits the footprint may still differ in its ratings.
