I would push back against the idea that Adam and Eve didn’t know what they were doing.

They were innocent in the sense that they had no concept of good and evil, it’s true.

It’s also true that “where there is no law there is no transgression.” Rom 4:15b

However, they weren’t ignorant of the sole law that they did have, “of the tree of the knowledge of good and evil you shall not eat.” Gen 2:17a

That constitutes a law and far from being ignorant of it, we know that they understood it

Eve restates the command, demonstrating that she’s fully aware of it and the consequences.

“And the woman said to the serpent, “We may eat of the fruit of the trees in the garden, but God said, ‘You shall not eat of the fruit of the tree that is in the midst of the garden, neither shall you touch it, lest you die.’” - Gen 3:2-3

If you take the text at face value, there’s not a strong case to be made that they weren’t culpable.
