Questions

Is there a KiCad symbol and footprint for the PCA9557DB?

Yes. The symbol is Interface_Expansion:PCA9557D and the footprint Package_SO:SSOP-16_5.3x6.2mm_P0.65mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the PCA9557DB?

SSOP-16-208mil, with 16 pins. Its footprint is drawn on this page.

Where is the PCA9557DB datasheet?

Texas Instruments publishes it: the Datasheet link on this page opens it.

Where can I order the PCA9557DB?

JLCPCB lists it as part C1542535, with 0 in stock; the sellers' links on this page open their listings.

What can replace the PCA9557DB?

Parts like it in the library: the PCA9534DBR by Texas Instruments, the PCA9534ADB by Texas Instruments, the PCA9538DB by Texas Instruments and the PCA9554DB by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.
