I learned French, now living in France. I took a course to pretty much improve my accent and to not rely on translation when speaking. Our teacher never spoke English to us since day one, using images instead to relay messages.

What really helped me enforce what I learned is talking to real people online. There are plenty of groups in Discord where you can have conversations with people of different backgrounds and personalities, where you can capture vocabulary used by French speakers every day.

LLM is like Duolingo, you cannot rely on it alone. The OP cancelled their French course for this. You can use it but make sure to have different active and passive learning methods.
