IANAL but my understanding is that contrary to US, several EU countries have limitations to what on can claim in court. Claim can not exceed damage. If you burn yourself with a hot coffee in a mc donalds your medical expense will covered and you might get a couple hundreds or a thousand while in the US you can be awarded millions in punitive damage by a jury.
This limitations means there's less frivolous litigation in the EU, unless it's a rich person or entity trying to silence someone, then they will waste money on frivolous litigation until the other party is unable to take it anymore (SLAPPs) a well known example of this is what happened to journalist Denis Robert who went through 10 years of multiple litigations in several countries for daring to expose the money laundering scheme happening in the European banking system in Luxembourg.
FYI, there are no lawsuits with GDPR: You file a complaint with the relevant data protection agency and they then decide whether to pursue this. Should they do that, the company can dispute the claim and only then elgal proceedings would follow (agency v company, no potential award for person filing complaint)
Lawsuits are used in a lost of western and eastern countries to try and right wrongs. Many of them use lawsuits to troll and money grab as well. It's not unique to the US.
