Questions

Is there a KiCad symbol and footprint for the LM57FPW?

Yes. The symbol is EasyEDA_Cloud:LM57FPWR and the footprint Package_SO:TSSOP-8_4.4x3mm_P0.65mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the LM57FPW?

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

Where is the LM57FPW datasheet?

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

Where can I order the LM57FPW?

JLCPCB lists it as part C2864972, with 0 in stock; the sellers' links on this page open their listings.

What can replace the LM57FPW?

Parts like it in the library: the LM57TPW by Texas Instruments, the LM57TSPWRQ1 by Texas Instruments, the LM57FEPWQ1 by Texas Instruments and the LM57FQPWRQ1 by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.
