Mod conflict detectors aren't particularly helpful anyway unless you already have an idea what you're looking for. I use the one that is part of Sims 4 Tray Importer and it reports something like 67 'conflicts' in my current setup, for example. But it's all good and everything works fine for me.
What I use them for is to identify a problem where I already know sort of what I'm looking for but just don't know which mod(s) specifically. Like if Mod A is not working right, I'll look for what other mods have some overlap (i.e. conflict) with Mod A.
With the issue you're having, I'd rely more on the batch testing solution already discussed. I had the same issue as what you're having way back in the early days of the game and ended up opting to remove one mod completely because it caused the problem after almost every game update which added food recipes.
