Questions

Is there a KiCad symbol and footprint for the LF256H?

Yes. The symbol is Amplifier_Operational:LF256 and the footprint Package_TO_SOT_THT:TO-99-8, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the LF256H?

TO-99-8, with 8 pins. Its footprint is drawn on this page.

Where is the LF256H datasheet?

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

Where can I order the LF256H?

JLCPCB lists it as part C1346405, with 5 in stock; the sellers' links on this page open their listings.

What can replace the LF256H?

Parts like it in the library: the AD547LH by Analog Devices, the AD744TH/883B by Analog Devices, the OP17EJ by Analog Devices and the TL062MLB by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.
