Henbit toxic to sulcatas?

[Dudley The Sulcata]

I have let my Sulcata roam around my yard and eat pretty much whatever plants he wants. I am 99.99% sure he has eaten henbit. After finding a post about henbit being toxic to sulcatas, I did a little research and I am finding conflicting answers. Help! If it is toxic, What will happen to Dudley? :/

If you scroll down to the 42 plant listed, you will find it here on this Russian Tortoise food list....outside of that, I could not find anything relating the plant to Sulcata specifically....

I did also find this---read specifically the second paragraph near its end;
