I was wondering, when compilers output to CIL, is the CIL optimized? Assuming the language doesn’t insert bonus data information in debug mode i was wondering if the JIT does all optimizations completely by itself and i assume it could.

Both. If you build in release mode, whichever compiler you’re using will apply some optimization to the code before it goes into CIL. The JITter has optimizations too.
An example of an optimization typically done by the compiler is constant folding.
An example of an optimization typically done at JIT level is loop unrolling.
