Accidental tomato plant – can I transplant?

Hi all – I used to keep my compost bin next to my outside stairs and I must’ve dropped some tomato scraps next to the bin. I just found out I now have an accidental tomato plant! This is so exciting bc it’s my first veggie plant ever!
Anyway, it’s getting colder out, temps will be dropping, and I’m not optimistic it will survive. Can I (or should I) transplant it to a pot and bring it inside? Or should I just appreciate the time I have left and let nature take its course? For what it’s worth, there are two more seedlings at the base of this plant, neither with flowers.
Any advice and thoughts would be so helpful. Thanks in advance!
