How can Pi be both infinitely long and non-repeating?

I don't get it. If it's infinitely long, wouldn't it just repeat an infinitely long string of numbers an infinite number of times?

You can't repeat an infinitely long string of anything.  It's infinitely long.

That being said, a good way to imagine this is this number:

1.23456789101112131415161718192021222324252627282930..... (and so on)

It should be obvious that you'll never be able to point at a chunk of digits in this number and say "from here on out, this pattern repeats forever".  Since you can't do it in this case, this number is a non-repeating decimal, which means it's also irrational.  Pi is another number like this, it's just not as obvious that it doesn't repeat eventually.
