The requirements for conversion of an ICAO CPL/IR to an EASA CPL/IR are laid out in Commission Delegated Regulation 2020/723

You don't get any "reduced hours" based on your nationality. This is irrelevant.
You'll need to do something like this (it may not be exactly the same, but as an outline):
- Choose the EASA MS (member state) you wish to work with. You can pick any EASA MS you want; don't go with Italy just because you're Italian. I recommend Austria and Denmark as they are efficient and pragmatic.
- Get a Class 1 Medical in an EASA AMC (Aero Medical Centre), issued by your EASA MS of choice.
- Get an EASA ELP (English Language Proficiency) certificate issued. If you go with AustroControl, they publish a list of approved ELP providers many of whom can do this test online for you.
- Have your ICAO Radio-Telephony certificate approved/converted by the EASA MS.
- Go to an EASA ATO and have them assess your case. Based on your flying experience, they will create a training programme for you. This is the "training as required by the ATO" bit, but it's sensible to have the EASA MS authority confirm to you in writing that they approve of said training programme.
- Complete the training programme and then do two skills tests: CPL(A) and ME/IR
As a note: the EASA CPL training and CPL skills test do NOT have to be completed in EASA airspace. The same is not true of the EASA IR, where "some" of the training has to take place in EASA airspace, and the EASA IR skills test HAS to take place in EASA airspace.
Pick an ATO that is known for ICAO to EASA conversion. Most ATOs in Europe are more comfortable dealing with ab-initio students and don't like to or don't know how to deal with students who like you hold non-EASA flying qualifications.
When they elaborate a training plan for you, ask what they are basing it at. You don't want an ATO that makes you fly 50 multi-engine dual hours just to get business out of you. It's possible they may ask for an "assessment flight" with an instructor to see where you're at, this is reasonable.
