IDE is an Integrated Development Environment. So I think strapping a few tools together with no real influence over one another doesn't seem to constitute an IDE.
Unless you wanna argue that putting these tools into a Docker image makes that container an IDE, then I don't know, maybe? Whatever floats your boat in the end.
Using a JetBrains product you pretty much just pay for the support and "works out of the box" features. You can roll your own LSP, AST Analyzers, shell scripts that bundle it all together and call it an IDE, but I would still be on the side saying it's just a bunch of tools and they're not "integrated"
