LUKS is not broken. An old KDF option in LUKS for encrypting the master encryption key in a keyslot is just old and less safe than newer, better KDF options.

afaik LUKS1 is fine. And AES is fine.

What matters is which KDF is used in your luks slots (which hold your AES master encryption key)

PSA: Upgrade your LUKS PBKDF to Argon2id !! (tails.boum.org)
 

TIL the French government may have broken encryption on a LUKS-encrypted laptop with a "greater than 20 character" password in April 2023.

When upgrading TAILS today, I saw their announcement changing LUKS from PBKDF2 to Argon2id.

The release announcement above has some interesting back-of-the-envelope calculations for the wall-time required to crack a master key from a LUKS keyslot with PBKDF2 vs Argon2id.

And they also link to Matthew Garrett's article, which describes how to manually upgrade your (non-TAILS) LUKS header to Argon2id.
