Does this board have esp32 chip included on the dev board or is this meant to sit on top of an esp32 dev board like a wroom or similar?

This development board already contains esp32 chip, you can refer to the detailed picture for the location of the chip

Do you sell a replacement lcd screen? I didn't realize how fragile they are and I cracked mine.

Dear customer, we have LCD screens sold separately. You can replace them. Please contact the customer service team for details jialing@lilygo.cc Thank you

This is not ESP32-S3, ESP32-S3 is amazon.com/dp/B0B7X5RVTH?ref=myi_title_dp

How do the mcus communicate between each other? is there example using i2c or spi or can? no point in buying two mcus and use only one

The MCUs would communicate with each other via WiFi or Bluetooth. I2C, SPI and can are used to communicate with peripherals such as sensors or displays. One could have devices with temperature/humidity sensors at different places in your environment using the on-board display to show the temperature at that location and have the device send the values to a central location periodically.
