Yeah, sort of, (for the lack of anyone else replying) I briefly worked with a young boy with ASD he hadn't been formally diagnosed with ODD but if you gave him a direct instruction he would often refuse flatly to do what you asked. I don't mean when asking him to stop doing something naughty but more 'we're all going to sit down and write our poems now'
After a while of watching and noticing patterns I started to feel like at the root of this refusal was anxiety. I really only worked with him for a few months but I was just starting to get to know how he expressed stress and noticed there was often similar actions and facial expressions.
It seemed to be better to come up with more creative ways, like doing the thing and asking him to help 'oh I don't know if I'm doing this right, what do you think?' or asking him and if he refused, not responding and letting him just get involved in his own sweet time. or suggesting he could just have a little go and stop if it wasn't working for him. The two factors here were, first of all he was 6 years old, which meant he was quite easy to dupe -any older and he may have been able to see through my pretty rudimentary tricks -or if i'd have been around long enough to do them a few more times and for the novelty to wear off. And sometimes it was hard to come up with an interesting way to hoodwink him into doing something, or circumstances didn't allow for it.
But it definitely really helped when I realised he wasn't just refusing to be rebellious or attention seeking, I felt like I understood it better and I found it easier to tackle.
I hope that helps, like I said earlier I don't know if it was ODD but it seemed like it might be
