I think Cruella was more likely leading Le pelt on as she needed him to make her Dalmatian coat. But it is really hard to determine her true intentions toward the man when she said in the first film that men were basically nothing while talking to Anita.
"More good women are lost to marriage than war, famine, disease and disaster."
She said. "You have talent darling. Don't squander it!"
But as I said we're not aware what Cruella's intentions really are except that she wants her spotted Dalmatian puppy coat with a hood.
"Muhahahahahahahaha! Surprise! Earlier than I planned but c'est la vie!"
Cruella De Vil

yeah, i've always thought they had a thing going on
"If you gotta go, go with a smile!"
