That is a bit of a problem! They are 1.27mm 'half pitch', where 2.54mm is the standard 0.1" U.S. DIP package size.
The LilyGO schematic says 'PZ127-2-15-S'.
Your board also has two Qwiic I2C connectors and supplied ribbons!
All of my projects are I2C, but you can program the four I2C pins on the ribbons to be GPIO for LEDs and switches.
The LilyGO T-Display S3 with soldered headers is a much better board for experimenting and education, IMHO.
