I have done some more googling (I can’t stress this enough, I am just googling)

The top alternatives are rFC (genetically modified cells produce the required enzyme) and MAT (human monocytes do the detection) They’re more costly, picking ready fruit is easier than growing an orchard.

Also I should mention how new the alternatives are, they’re just (2018 is just now for me lol) getting their approvals and regulations so given time LAL will be replaced.
