Questions

Is there a KiCad symbol and footprint for the TMS320LC31PQL?

Yes. The symbol is EasyEDA_Cloud:TMS320LC31PQL and the footprint EasyEDA_Cloud:PQFP-132_L27.8-W27.8-P0.64-LS27.4-TL, both drawn on this page. PCBKit places them on a board for you when you design with it.

Where is the TMS320LC31PQL datasheet?

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

Where can I order the TMS320LC31PQL?

JLCPCB lists it as part C3588430, with 0 in stock; the sellers' links on this page open their listings.

What can replace the TMS320LC31PQL?

Parts like it in the library: the TMS320C51PQ by Texas Instruments, the TMS320C51PQ100 by Texas Instruments, the TMS320C51PQ57 by Texas Instruments and the TMS320C51PQA57 by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.
