Replacing the alternator does ot involve any component that would leak oil.
If the oil is red or clear, it could be a power steering hose that is leaking.
If it is engine oil, the likely source would be the crank pulley seal.
Without a visual inspection, it would not be possible to determine if the alternator replacement had anything to do with it.
