Is there a KiCad symbol and footprint for the LED1642GWXT?

Yes. The symbol is Driver_LED:LED1642GWXTTR and the footprint Package_SO:HTSSOP-24-1EP_4.4x7.8mm_P0.65mm_EP3.2x5mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the LED1642GWXT?

TSSOP-24-EP, with 25 pins. Its footprint is drawn on this page.

Where is the LED1642GWXT datasheet?

STMicroelectronics publishes it: the Datasheet link on this page opens it.

Where can I order the LED1642GWXT?

JLCPCB lists it as part C2678706, with 0 in stock; the sellers' links on this page open their listings.

What can replace the LED1642GWXT?

Parts like it in the library: the LED1642GWT by STMicroelectronics, the STP04CM05XT by STMicroelectronics, the ALED1262ZT by STMicroelectronics and the LED1642GWP by STMicroelectronics. Check their datasheets: a part that fits the footprint may still differ in its ratings.
