This is complicated for me to explain 😢😂 but I will try!

When you say “a chill ran down his spine”, it means that something made the person uneasy. When you give someone the creeps, you make them feel uneasy overall - everything within them says not to trust you.

When someone has a chill down their spine, you can kind of think of it as them feeling cold travel through their body. That is a chill (noun), but to feel that experience is the chills.

In English, we don’t say that someone has a creep (a creep is what we call someone who is creepy —> “that guy is such a creep!” Vs “he gives me the creeps.”)

Example
You’re walking alone at night and you see someone nearby who looks sketchy (like trouble). A chill travels down your spine and you get the chills (the hair on your arms/neck stands up, you get goosebumps... the effect is plural, it encompasses multiple parts of your body).
