It’s important to remember the ‘end use’ on the content provided. Assuming you’re using Revit as a design tool, the dimensions you specify in the documentation all come with some degree of flex in tolerances.
Construction tolerances for a framed wall are typically afford a tolerance of 1/2" in 32". More restrictive values for something like a concrete slab are in the range of 1/2" over 120". With those tolerances the angle to 'put a constructed wall out of compliance with that number is 0.895 degrees, and the value to put a slab with out of compliance is 0.23. Both of which are outside of Revit’s trigger for this warning which is about 0.22 degrees.
Of course there are aspects of some trades who have higher level of accuracy (ie: a class A floor slab has a maximum deviation of 1/8" in 120" which results in 0.05 - about 1/4 of Revit’s limit, though that’s for a level plane not the ‘edge’ of the slab).
In the end I find that 99% of the time if you step back and abstract the building keeping ‘what the guys in the field can do with this’ in mind, you’ll find that you have less ‘off axis warnings’ than you think.
Edit: adding a useful graph to calculate what the angle is given two tolerance values:
