Questions

Is there a KiCad symbol and footprint for the FSQ311L?

Yes. The symbol is EasyEDA_Cloud:FSQ311L and the footprint EasyEDA_Cloud:LSOP-8_L9.2-W6.4-P2.54-LS9.6-BL, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the FSQ311L?

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

Where is the FSQ311L datasheet?

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

Where can I order the FSQ311L?

JLCPCB lists it as part C3094463, with 0 in stock; the sellers' links on this page open their listings.

What can replace the FSQ311L?

Parts like it in the library: the FSQ0165RL by onsemi, the FSQ0365RL by onsemi, the FSQ0265RL by onsemi and the FSQ321L by onsemi. Check their datasheets: a part that fits the footprint may still differ in its ratings.
