Questions

Is there a KiCad symbol and footprint for the PCA9538DGV?

Yes. The symbol is Interface_Expansion:PCA9538D and the footprint Package_SO:SO-16_3.9x9.9mm_P1.27mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the PCA9538DGV?

TVSOP-16-4.4mm, with 16 pins. Its footprint is drawn on this page.

Where is the PCA9538DGV datasheet?

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

Where can I order the PCA9538DGV?

JLCPCB lists it as part C2669730, with 0 in stock; the sellers' links on this page open their listings.

What can replace the PCA9538DGV?

Parts like it in the library: the PCA9557DGV by Texas Instruments, the PCA9555PW by Texas Instruments, the TCA9555DB by Texas Instruments and the PCA9534DBR by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.
