Many would agree with the OP's connection such as Benson:
Gen 8:21 - ... I will not again curse the ground — Hebrew: I will
not add to curse the ground any more. God had cursed the ground upon
the first entrance of sin, Genesis 3:17; when he drowned it he added
to that curse: but now he determines not to add to it any more.
The Pulpit commentary is slightly more nuanced:
I will not again curse the ground any more for man's sake. Literally, I will not add to curse. Not a revocation of the curse of
Genesis 3:17, nor a pledge that such curse would not be duplicated.
The language refers solely to the visitation of the Deluge, and
promises not that God may not some. times visit particular localities
with a flood, but that another such world-wide catastrophe should
never overtake the human race.
Thus, while the flood of Noah was to some degree a result of sin generally, it was primarily the sin of the antediluvians, not just Adam and Eve's original sin. The reason for the flood is explicitly recorded in Gen 6:
5 Then the LORD saw that the wickedness of man was great upon the earth, and that every inclination of the thoughts of his heart was
altogether evil all the time. 6 And the LORD regretted that He had
made man on the earth, and He was grieved in His heart. 7 So the
LORD said, “I will blot out man, whom I have created, from the face of
the earth—every man and beast and crawling creature and bird of the
air—for I am grieved that I have made them.”
