Yes. The symbol is Amplifier_Operational:LM318M and the footprint Package_SO:SOIC-8_3.9x4.9mm_P1.27mm, both drawn on this page. PCBKit places them on a board for you when you design with it.
SOIC-8, with 8 pins. Its footprint is drawn on this page.
Texas Instruments publishes it: the Datasheet link on this page opens it.
JLCPCB lists it as part C1347159, with 0 in stock; the sellers' links on this page open their listings.
Parts like it in the library: the LM358D by onsemi, the LM2904D by onsemi, the NE5532D by Texas Instruments and the LM358D by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.
