I heard people talking about double seed phrases so like 48 word phrases instead of 24 but I have no clue how that works wish I did.

Haven’t heard of that, but you could use a 24 word seed phrase as the pass phrase. I think that would actually be more entropy than a 48 word phrase (based on my understanding that the entire pass phrase is used, in contrast to just the first four letters of each word in the seed phrase)
Multisig is a solution
