As far as the content of the EULA, sure, use the laws of the request’s IP address; the rest of the website, however, does not allow you to select a different localization, only the place of origin.

Furthermore, rarely do I see EULAs that aren’t written in English, and it’s not like the EULA in question is not a generic one translated for my country:

[…] [non] influiscono su eventuali garanzie o garanzie legali dell’utente in qualità di consumatore ai sensi delle leggi locali applicabili (ad esempio, diritti dell’utente in caso di malfunzionamento del Software)

Non-lawyerly translation:
[…] [do not] affect the legal rights of the user as a consumer accoring to local applicable laws (for example, the rights of the user in case of Software malfunction)

… which means either someone bothered localizing a generic EULA, or that excerpt is the legal version of “unless it’s illegal idk im not a lawyer”.
