Nice to see other people working on similar projects, it looks very promising
Sorry, I don't know any chip that integrates multiple stepper drivers + controller all in one.
If you are looking for a motion controller alone to use with your Pololu stepper driver modules, I started my project using the TMC429-LI, it sends step/dir pulses for up to 3 stepper drivers, uses SPI as interface and handles the end-stop switches, maybe it works for you. I finally preferred to use multiple TMC5130 because the motion controller is integrated and simplifies the PCB, it can use SPI or UART as interface.
