Is there a KiCad symbol and footprint for the SI2401-FSR?

Yes. The symbol is EasyEDA_Cloud:SI2401-FS and the footprint Package_SO:SOIC-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 SI2401-FSR?

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

Where is the SI2401-FSR datasheet?

Silicon Labs publishes it: the Datasheet link on this page opens it.

Where can I order the SI2401-FSR?

JLCPCB lists it as part C2649393, with 0 in stock; the sellers' links on this page open their listings.

What can replace the SI2401-FSR?

Parts like it in the library: the XL1192S by XLSEMI, the ISL32273EIBZ-T by Renesas Electronics, the DS2482S-800+ by Maxim Integrated (Analog Devices) and the MS1192 by Hangzhou Ruimeng Tech. Check their datasheets: a part that fits the footprint may still differ in its ratings.
