In first version of PCB there is a bug that leaves U6 Vss/Vdd pins floating and U5 Vdd floating:

The TL072IP is a FET Input Amplifier made by Texas Instruments in a PDIP-8 package with 8 pins. -15V~-5V、5V~15V -40℃~+85℃ 1.4mA 100dB 13V/us 18nV/√Hz@1kHz 18uV/℃ 2 3MHz 3mV 5pA 65pA Short-Circuit Protection、Built-in compensation、Latch-up suppression PDIP-8 FET Input Amplifiers ROHS.
PCBKit's library has its KiCad symbol (Amplifier_Operational:TL072, from KiCad's library) and its footprint (Package_DIP:DIP-8_W8.89mm_SMDSocket_LongPads, from KiCad's library), ready for a KiCad board. 1,380 are in stock at JLCPCB (part C110329). 5 open-source boards in 5 repositories on GitHub use it.

PDIP-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 C110329, with 1,380 in stock; the sellers' links on this page open their listings.
Parts like it in the library: the TL072CP by Texas Instruments, the TL081CP by Texas Instruments, the TL071CP by Texas Instruments and the TL072CN(LX) by lingxingic. Check their datasheets: a part that fits the footprint may still differ in its ratings.
