There could be several factors contributing to the brittleness of your prints. It's great that you've already ruled out a clogged nozzle and tried different filaments. Here are a few other things you can check and troubleshoot:

Temperature: PLA filament typically prints best between 190-220°C. Make sure your print temperature is within this range. If it's too hot, the filament can degrade and become more brittle.
Cooling: Excessive cooling can also lead to brittle prints. Check your cooling fan settings to ensure they are appropriate for PLA. It's generally recommended to have a part cooling fan running at around 50-100% for PLA.
Filament quality: Poor quality or older filament can become brittle over time, especially if not stored properly. Make sure your filament is stored in a dry environment and consider trying a fresh spool to see if the issue persists.
Layer adhesion: Poor layer adhesion can result in weak points within the print. Try increasing your bed temper...
