The symbol is Amplifier_Operational:LM2904 and the footprint Package_SO:SOP-8_3.76x4.96mm_P1.27mm, both drawn on this page. PCBKit places them on a board for you when you design with it.
SOP-8, with 8 pins. Its footprint is drawn on this page.
GOODWORK publishes it: the Datasheet link on this page opens it.
JLCPCB lists it as part C51912399, with 40,051 in stock; the sellers' links on this page open their listings.
Parts like it in the library: the LM358DR91M by GREENMICRO, the LM358P8 by hongjiacheng, the LMV358AIDRG4 by HANSCHIP semiconductor and the NJM4558LDRG4 by HANSCHIP semiconductor. Check their datasheets: a part that fits the footprint may still differ in its ratings.
