If he really wanted to let Lily live, he would have stunned her, or he would moved to cast the Killing Curse on the crib without harming her.
That’s true enough.
But I don’t think keeping his deal with Snape required making sure that Lily lived, it required giving her a chance. You say it was a crappy chance. Maybe so. But this was a concession on Voldemort’s part, and expecting a Dark Lord to do more than the letter of an agreement is asking a bit much.
