It's silly to have to keep repeating this, but for sake of the slow learners in the back of the class here are all of the verses in Job that say sons of God in the MT and angels of God in the LXX. Since the MT and the LXX are both scripture and these verses in each contradict each other, this renders Job inadmissible as evidence, and consequently a main pillar, actually probably the main pillar, of the sons of God argument falls.
Now there was a day when the sons of God came to present themselves before the LORD, and Satan came also among them. Job 1:6 (MT)
And it came to pass on a day, that behold, the angels of God came to stand before the Lord, and the devil came with them. Job 1:6 (LXX)
Again there was a day when the sons of God came to present themselves before the LORD, and Satan came also among them to present himself before the LORD. Job 2:1 (MT)
And it came to pass on a certain day, that the angels of God came to stand before the Lord, and the devil came among them to stand before the Lord. Job 2:1 (LXX)
When the morning stars sang together, and all the sons of God shouted for joy? Job 38:7 (MT)
When the stars were made, all my angels praised me with a loud voice. Job 38:7 (LXX)
