This is the special damage power from GotG Starlord 030

"TACTICAL MANEUVER: Star-Lord can use Outwit. When he does, he can count range and draw lines of fire from any friendly character that shares a keyword with him."

The question is if him and similar character draw line of fire from a giant friendly character, would these characters in turn have the line of fire of a giant figure?

This is the only similar thing I can find and leads me to believe that he is just counting it as if he was in that spot rather than being that actual character.

Does Star Lord have Giant Size from some effect?

No?

Then he draws lines of fire the same way he always does, no matter what powers or effects the character he is counting from has.
