"A growing number of people have figured out a trick to make AI tools tell you almost whatever they want. It's so easy a child could do it."
..taken from online news
to figure out = to invent - able to find
make ... tell = far sì che ti dica (in this case - tell)
-ever = qualsiasi: whatever qualsiasi cosa; whenever qualsiasi momento: wherever qualsiasi luogo etc...
easy that a child could = I can omit that because between that and could (verb) there is something in between
