Questions

Is there a KiCad symbol and footprint for the PCA8574APW?

Yes. The symbol is EasyEDA_Cloud:PCF8574DWRG and the footprint Package_SO:TSSOP-16_4.4x5mm_P0.65mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the PCA8574APW?

TSSOP-16, with 16 pins. Its footprint is drawn on this page.

Where is the PCA8574APW datasheet?

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

Where can I order the PCA8574APW?

JLCPCB lists it as part C55762, with 0 in stock; the sellers' links on this page open their listings.

What can replace the PCA8574APW?

Parts like it in the library: the PCA9554PW by NXP Semiconductors, the PCA9557PW by NXP Semiconductors, the TCA9534PW by Texas Instruments and the TCA9534APW by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.
