Is there a KiCad symbol and footprint for the PCA9546APW?

Yes. The symbol is pimoroni:PCA9546A 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 PCA9546APW?

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

Where is the PCA9546APW datasheet?

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

Where can I order the PCA9546APW?

JLCPCB lists it as part C400705, with 6,104 in stock; the sellers' links on this page open their listings.

What can replace the PCA9546APW?

Parts like it in the library: the PCA9546APW by NXP Semiconductors, the IP2721 by INJOINIC, the SC18IS606PWJ by NXP Semiconductors and the SC18IS602BIPW/S8HP by NXP Semiconductors. Check their datasheets: a part that fits the footprint may still differ in its ratings.
