Sister website Wiktionary says that ιώτα is an alternative form of γιώτα. I assume γιώτα is used because <γ> sounds roughly like a consonantal i before /i/ and /e/ sounds (in other words, almost like English <y>). Not exactly, but close. I also assume that in Ancient times ιώτα would be pronounced with the <ι> sounding like English <y>, so Modern Greek uses <γι> to approximate the sound.
Someone smarter: confirm or deny my suspicions!
The pronounce "ιώτα" can be found in the Bible as it is in "ἰῶτα ἓν ἢ μία κεραία" (Mathew, 5:18) https://www.biblegateway.com/passage/?search=Matthew+5:17-18, meaning the smallest letter in this case. As ι is really the smallest letter in the alphabet and it is like an antenna (κεραία) in shape
There is nothing abnormal about Greek letters, or inherently normal about Latin ones. I assume you mean how can you use Latin letters .... See Writing in Greek and Greeklish https://www.duolingo.com/comment/17556409 which gives details of how the use modified transliteration, although it is of great benefit to use the Greek alphabet and this post on hiw to add a Greek keyboard gives some helpful links https://www.duolingo.com/comment/17706271 whilst this one on Modern Greek resources is also very helpful https://www.duolingo.com/comment/17509582

Ok, let's see why we show these words and what they mean:
"Each letter in the Greek alphabet has a name so "γιώτα" is the word that means the letter i or when we say "kappa" we mean Κ etc. The way we say "double u" for W."
These words will also help you get used to the sound and spelling of Greek words. If you are already familiar with the look and sound of the Greek alphabet you can move on to the next Skill.
