This OP got it working.
https://forum.arduino.cc/t/touch-not-working-with-esp32s3-ili9341/1231572
looking at the post I cannot see any mention of which graphics library is being used
I have the ESP32S3/IL19341 combination working with the Adafruit_ILI9341 library OK - the problem appears to be with using TFT_eSPI library on the ESP32S3
I saw this.
Do you see any CLK or DATA pulses on the ESP Pins?
made some progress

Much more than progress , its working proof that ESP32S3 will work with TFT eSPI.
Sadly the OP left 2 days ago.
the problem with it only working with ESP32 core 2.0.14 is a real pain!
True words spoken!
there was mention of using a ESP32C3
this test used a ESP32-C3-MINI-1 running TFT_eSPI on a IL19341

similar problems to ESP32S3 in that ESP32 core 2.0.14 works OK but ESP32 core 3.2.0 goes into a reset loop
Dude, you are a 100% professional in this area. Your tip solved the problem! I hope you make decent money on this if you haven't started yet. There is no such information even on YouTube!
And the TFT_eFEX companion library, for displaying images on the TFT, does not compile on the newer ESP32 cores.
some more tests
been unable to get touch tests to work on ESP32S3 or ESP32C3 using

my notes indicate I had touch working with an ESP32
positive news: I have the TFT display onboard SD card reader working with both the ESP32S3 and ESP32C3
