Your AI generated circuit is bogus. You can't generate RGB just from GPIOs 17, 22, and 24, and SCART wants sync signals as well.
You can generate analogue RGB from the DPI block using a resistor ladder, effectively equivalent to the VGA666 adapters that have a VGA output connector. SCART generally wants a composite sync (horizontal and vertical combined) rather than the discrete horizontal and vertical syncs that VGA produces, so you would need additional circuitry to combine them.
There are a couple of DPI to SCART adapters around though, eg http://pi2jamma.info/pi2scart , https://www.recalbox.com/recalbox-rgb-dual/, and https://www.rgb-pi.com/
Do note that these are all only 18bit RGB (aka RGB666), so 262k colours rather than the 24bit/16.8m colours that most other displays would run with. You probably don't want to watch movies on it, but for retro gaming it is generally very usable.
