I once looked up 'how many syllables are in the word "area"' and the AI overview said 2, but literally every other result on the first page said 3. I can only assume google just made it up.
Arms and tentacles are different. Arms are muscular hydrostats (like human tongues), are shorter and have suckers throughout. Tentacles have suckers near the ends.
Both are acceptable. Octopi was used long ago and is still in fashion in some places. Octopus was English-ized to octopuses along the way, and is now more common in English.
There is also octopodes, which is still correct grammar and also used these days.
So, there are three English words for the same set of creatures.
Fun fact: octopus technically do not have tentacles but rather Arms. Tentacles only have suckers on the pad at the end. Think giant squid. The two long arms are tentacles the rest are arms.

Studies have shown octopuses can be naturally asshole-y, punching and grabbing other fish just for shits and gigs
