Why is it so hard to find interlinear translations of Latin authors?

Seriously, why is it nearly impossible to find decent interlinear translations of Latin authors online? I mean, for a language that's been studied for centuries, you'd think there would be more accessible resources for learners and enthusiasts.

I’m specifically looking for interlinear translations (word-by-word) of Latin authors—any authors! Ideally in Italian, but English works too. If anyone knows of any online resources or even books that fit the bill, please share!

It’s wild how many texts are locked behind academic walls or buried in obscure editions. Latin shouldn't be a secret society; it should be for everyone. Help me find these, please.
