Questions

Is there a KiCad symbol and footprint for the FSQ311?

Yes. The symbol is EasyEDA_Cloud:FSQ311L and the footprint Package_DIP:DIP-8_W8.89mm_SMDSocket_LongPads, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the FSQ311?

DIP-8, with 8 pins. Its footprint is drawn on this page.

Where is the FSQ311 datasheet?

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

Where can I order the FSQ311?

JLCPCB lists it as part C3094656, with 0 in stock; the sellers' links on this page open their listings.

What can replace the FSQ311?

Parts like it in the library: the ICE3BR0665JXKLA1 by Infineon Technologies, the ICE3A2065ELJFKLA1 by Infineon Technologies, the ICE3A1065ELJ by Infineon Technologies and the KA5M0165RN by onsemi. Check their datasheets: a part that fits the footprint may still differ in its ratings.
