The lds-org denies that Jesus is the Creator, that everything was created THROUGH Him, BY Him and FOR Him.
Well, Lds "scriptures" mention Jesus as the Creator (they simply redefine what "creator" means...see #2 below). But your reference of Col. 1:16-17 also "sticks" from another angle...(I've quoted it to Mormons often). It's the part of v. 16 that says "ALL THINGS were created by Him."
#1, Mormons don't believe Jesus created the angels.
#2, technically speaking, you're right in that Mormons don't truly honor Jesus -- or God, for that matter, as "Creator." How can we say that?
(a) They weren't prior to the existence of many entities, spirits, elements, and intelligences (D&C 93:29,33).
(b) As such, Mormons redefine "creator" to = "organizer."
They don't believe God created anything out of nothing.
And they believe that you, me, vegetation, the beast in the forest were all as eternal past as any other entity -- including the spirits who eventually became the gods.
