I have a huge file to read, more than 5GB. I need to do some transformation over each line, convert into my data object and than persist. File.forEachLine is a good choice for that?

The function is correct, but I'd recommend using Path.forEachLine instead. Manipulating Path is usually preferred over File in new code

Note that Kotlin provides lots of useful extensions on Path that make it much more convenient to use than Java's Files.doSomething(Path)
