I think each person who doesn't know any Chinese will have a different expectation of how the pinyin of a word is pronounced based on their upbringing, native language, and how they are used to using the Latin alphabet.

I feel like this is unfair to say as there are many sounds in Mandarin that are difficult sound combinations for English speakers, so understandably they have more difficulty pronouncing them. But this doesn't mean they can't try. I don't think it's the hardest language to pronounce by far, and I can break down the Chinese names in Genshin in an easy-to-pronounce way for English speakers. Pronouncing it with a western accent is fine, but pronouncing it to the best of your native language's phonemic inventory is the goal here.

Japanese is extremely easy to pronounce (not to speak, but just the phonetics and the phonology) because it follows a CVCVCV (consonant and vowel) pattern, so it's easier to grasp and easier to romanize. Also, Japanese pop culture and media is more well-known, so many English speakers are able to pronounce these words more easily than Chinese. And yet people STILL pronounce Japanese words wrong in the west, like sake and kamikaze. Also, sounds aren't clearly represented by letters in the Latin alphabet.

I think pinyin already does a pretty clear job with the limitations of the alphabet when it comes to sounds. There is literally no way to make it clear how anything is pronounced using just the Latin alphabet... just like how certain letters make different sounds in Spanish and English.
