The logs have a 2D model in the inventory but don't have a classic 3D model for general purposes(think vanilla 3D logs) and compatibility (ex. chisels and bits can't chisel them, little tiles chisels them but creates the no-model texture thing)

So there's two things here:

• if there's something specific that we do with our item / block model that breaks this, outside of "remove the log item textures", then by all means we can fix this. But I need to know what exactly that would be as as far as I can tell they use pretty bog standard models / blockstates to accomplish this.
• However, if the problem is just "if they use an item model / texture for the item (read: not the block, it functions perfectly fine in world)", then I'd rather not ditch our textures just for this.

I'll also point out it can be quite simply fixed by a resource pack

After having looking into our block model structure, I don't see anything out of the ordinary. It's all getting thrown away anyway in 1.15+ (due to forge blockstates being removed) so if this is an issue for the time being, use a resource pack. Otherwise, this is a nope.
