Perplexity Thread Deletion for multiple items
If you wish to delete multiple threads, use the Delete threads menu. This will remove all the threads you have created.

I don’t like this option because many threads are important, and I might want to go back and see them again. If you’re sure, click Delete threads and it will clear your account of all conversations in Perplexity.

I warn you that you might want to go back and see old threads later, so consider carefully before proceeding. I’m not going to proceed with this one, but the option is there if you want a completely clean slate.

Final Thoughts
You can delete individual threads from the Library via the three-dot icon, or from inside a thread using the top right menu. For a full cleanout, use Delete threads, but be cautious if you plan to revisit past conversations.
