Calling it now, Big Mom isn't going after Luffy right now, she's going to take Katakuri's soul as punishment for him failing to kill Luffy and solve the problem while she was on her rampage. Look at the way that conversation goes and it seems pretty clear to me, that's why perospero was hesitant saying that he's alive and has nowhere to run
