Pretty sure there are English JJK blurays. At least in the UK region. Can’t imagine there not being one for the NA region.
Edit: CR store has S1 and the movie https://store.crunchyroll.com/collections/jujutsu-kaisen/?prefn1=category&prefv1=Home Entertainment
S2 will most likely come out too, but not yet
Not sure, but maybe ‘Shikimori is not just a cutie’?
