could there be an irrational number that does not have one of the digits?

Yes, they all are like that. They need more decimal places because none of the digits are an exact match, so they use thr closest one under the actual value and then add another digit to get closer, but that digit only gets part of the way, so the same thing is done.
Irrational numbers keep doing that indefinitely. Some rational numbers, too, but they can be expressed as a fraction of exact numbers.
