Yes that is relevant. If you have Chrome installed, that means you installed Google on your Mac. It is not possible to use one without the other. Whether you actively use their Chrome product or not is irrelevant. Google will remain installed and will remain active until you uninstall it. It also updates itself in the background regularly, which makes it difficult to correlate the onset of poor performance to an overt action a user may have taken. A Mac that is performing perfectly well one day may perform poorly the next. Or, it might just damage its file system and render the Mac unbootable.
The specific answers to your questions can only be determined by asking the developer of those products, but general answers are as follows, in no particular order.
Why is it able to install itself in my log in items without any authentication or opt-in action on my part?
That is not correct. Although you may have done so years ago, you authorized Google to implement those system modifications by installing Google on your Mac. That consent gives it essentially unfettered ability to load, modify, update, and otherwise control how those system modifications operate and what they do. There is nothing new about that.
What is new — and what seems to be confounding unsuspecting users who did not perform their due diligence when installing those products — is macOS is now informing (or reminding) its users of that fact.
Nothing gets installed on a Mac without your consent. Nothing — although nefarious product developers successfully deceive people into doing that with disturbing regularity. Want something "free"? Click here! People do that all the time. Then they come here for help when they realize what they did was a terrible mistake. That's ok, it's what we're here for.
What is Google LLC login item?
Google apps such as Chrome are considered a "modern login item" as opposed to the traditional Login Items that preceded macOS 13. An introduction describing how developers such as Google can implement them is here: Manage login items and background tasks on Mac - Apple Developer.
It's also one reason I do not permit Google (or anything like it) to be installed on any of the Macs I own and / or control. It essentially relinquishes control of your Mac to Google, grants it nearly unlimited ability to harvest, upload, and subsequently sell your personal information and Internet activity — tracking your every move, every web page, every mouse click, every keystroke, building a picture of "you" and retaining it forever, thereby rendering nearly all the privacy advantages of using a Mac moot.
Those processes also burden a Mac for Google's sole benefit. Older and more resource-limited Macs are affected to a greater extent than newer, faster ones. If that means you have to buy a new Mac every few years to keep up with Google's constantly increasing demands, I suppose Apple won't mind. But Apple is sensitive to public perception (justified or not) that something may be happening with their products that may appear to be concealed.
I surmise this is the underlying motivation to provide this new notification that something was installed on that Mac that has the ability to affect its operation, or to circumvent the privacy Apple proclaims as a core aspect of their products and forms a cornerstone of their business model.
What is it doing?
"It" — meaning Google? It's making a lot of money, for Google, from selling you, as a product. Hopefully you already know that. It's common knowledge, it's been litigated, it's the world's worst kept secret, but if you want to learn more about that sorry state of affairs it's best to learn it from sources other than Google. They are very good at what they do.
So good in fact, that people argue in favor of it:
