In the USA most people are going to pronounce
Adeline to rhyme with "line" when they first see it.
If you don't like the spelling
Adelyn, there are other spellings that would more likely give you a -lin pronunciation. Have you considered Adelin, Adelinn, Addalyn, Adolin, Adylin, etc.?
Adalynn was actually the most common spelling of this name in the USA in 2022.
