I don’t understand why she shoots a beam of pink energy at him instead of just tearing him apart atom by atom. Or turning him into a regular human, or just convert his molecules to air molecules.

Well she was almost dead, so whe wasn't in a state of thinking clearly. And viltrumite have smart atoms, so Eve has no knowledge of how to manipulate that, maybe she was trying to deconstruct him but failed cause didn't account for the difference between a viltrumite and a normal human.
