Is there a KiCad symbol and footprint for the PCA9538DW?
Yes. The symbol is Interface_Expansion:PCA9538D and the footprint Package_SO:SOIC-16W_7.5x10.3mm_P1.27mm, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the PCA9538DW?
SOIC-16-300mil, with 16 pins. Its footprint is drawn on this page.
Where is the PCA9538DW datasheet?
Texas Instruments publishes it: the Datasheet link on this page opens it.
Where can I order the PCA9538DW?
JLCPCB lists it as part C2878559, with 50 in stock; the sellers' links on this page open their listings.
What can replace the PCA9538DW?
Parts like it in the library: the TCA9534DW by Texas Instruments, the PCA9534D,118 by NXP Semiconductors, the PCA9554ADW by Texas Instruments and the PCA9534DW by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.
