Guess I'll make my refutations here.
He didn't turn himself into order. The Order of the world was rewritten converting him into magic and magic is Overseen by Order which is what makes him a part of it.
Except it is clearly known. Nosgalia is the God that gives birth to Gods. Turning a human into a God goes against his Order, hence he made him a lesser part of it which was in line with his Order to destroy the Demon King.
Gods are so bound to Order that their actions cannot deviate from it. A God cannot do what is against their Order. For example, Nosgalia cannot attack Anos directly because his Order is to give birth to Gods.
Their actions are entirely bound to and decided by their Order to the point that Gods don't possess emotions, they don't have a mind, they are nothing, just Order.
In what way is the second scan vague? It directly says his Order is a fragment of that of the world. Jerga directly became a fragment of the worlds Order (Magic- the spell <Aske> to be exact).
I fail to see how a scan that literally says "The fate determined by the Gods" is referring to Law manipulation. "From my perspective" "it seems" none of that matters when it literally mentioned Fate.
"At no point does it say Order and Fate are the same". What is Order and what are Gods?
The beings who maintain Order- the beings who embody that Order- the beings that are the highest Order of natural law. That is a God. A God's power comes from Order, Gods are Order and their power is Order. If Gods have fate manipulation, that fate is Order.
The Order of Destruction is the end (MGK version of yogiiri)- it is death and destruction. As I've outlined above, a God's power cannot go against or do anything outside the jurisdiction of their Order.
Anos took away the Order of Destruction, turned it into something that destroys logic. The power to destroy logic isn't something the Order of destruction is capable of. So yes, the power of the Order of destruction was modified
A God's power is Order. This isn't giving resistance to the mechanisms of an ability, that mechanism is their ability. A God has no power of their own that isn't Order.
Eugo la Raviaz uses alters Order to stop time. Time stop isn't a separate application of Order, it is Order. Time wasn't just stopped. Concepts, Laws, Fate were altered directly to make time stop. To resist that requires directly resisting the other 3.
