[Star Wars] Why didn't the Jedi have a "defense against the Sith arts" class in the Jedi Temple?

Every Jedi thought the Sith were extinct. I feel like it would've been wise to still learn how to fight against the Sith or any dark side user just as a precaution should they return...even though they never left.

Because Jedi may have thought the sith extinct but dark jedi were still a problem. The darkside is extremely corrupting so even trying to understand it without a strong will can lead to your downfall. Many Jedi have fallen just by simply being in the presence of sith artifacts let alone trying to master their fighting styles and force abilities.
