Solution
This ended up being a troll question that surprisingly not many teams solved. Clearly, the numbers themselves were nonsense, but the lack of special characters, along with the fact that the description was unnaturally wordy, led me to casually check the first characters of each sentence (especially since two of them were 3 and 0, rather common 1337 characters). Sure enough, it spelt out ST3GL0LS, which was the flag.
