"bonnanj li pati, loloj li chavire" which one can be used for "crazy in love" as opposed to "crazy lunatic" or do you know some other expressions that I can use. thanks

I believe that you can use both unless there's something specific you want (or don't want) to imply..... such as you want to say "infatuation" instead of ..."crazy"
for example you could use:
Bonnanj li pati
Bonèt li chavire
Lòlòj li chavire
Tèt li pati
Tèt li fin cho
Li fin fou

as opposed to:
Li andyable
Li fin andenmon
Li fin anraje
etc....
