Well, if it did infringe on copyright to re-release a translation according to the law in your country, then you could have been litigated against no matter what the MD ToS is or has been.
In all practicality, and what has happened time and time again, is that the manga websites themselves get cease and desisted, not the individual scanlators. That was the biggest reason why MangaDex got re-worked to be a distributed P2P network in version 2, where people across the globe host the materials in different places, never touching the actual MD server itself, iirc-- as legal protection. (Since it was by far the most popular manga piracy site around at the time, even though now they give in to takedown demands)
I've never heard of a C&D leading to actual litigation. Usually the website just gets taken down, then someone else gets to host it somewhere else under someone else's name a couple of weeks later, on a different domain. I don't remember if that ever happened to MD, probably it didn't, but other sites I've seen this happen to many many times. Not just in manga, but movie streaming services, anime, TV shows etc.
Idk, I think your worries are unfounded, but you do you. Thanks for all your work thus far, it's been a pleasure 👋
