The use of "look at"

Sentence:

It is amazing that his first product does not look at all rudimentary.

Question:

I am confused about the use of "look at all rudimentary" here. Is it a special use of "look at"?

The phrase is being parsed incorrectly.

It's not an example of look at, but is as follows:

It is amazing that his first product does not look ^{at all} rudimentary.

Here, at all is an adverb, modifying the adjective rudimentary:

[Merriam-Webster]
: in any way or respect : to the least extent or degree : under any circumstances
// doesn't smoke at all

In other words, the sentence could be rephrased in the following way:

It is amazing that his first product does not look ^{in any way} rudimentary.
