it's hard for me to tell if the solution is correct or wrong because I've got next to no formal theoretical education in electronics and only the most basic 'pay attention to polarity of electrolytic capacitors' practical knowledge, but given how these things work you might get much better results when asking it to generate a spice netlist first (or instead).

I wouldn't trust it with 2d ascii art diagrams, there isn't enough focus on these in the training data is my guess - a typical jagged frontier experience.
