You need to set golangci-lint command to initializationOptions with --out-format json.

coc-settings.json

        "command": ["golangci-lint", "run", "--output.json.path", "stdout", "--show-stats=false", "--issues-exit-code=1"]
    }
  }
}

vim-lsp-settings provide installer for golangci-lint-langserver.

Requires Neovim v0.6.1 or nightly.

local lspconfig = require 'lspconfig'
local configs = require 'lspconfig/configs'
if not configs.golangcilsp then
 	configs.golangcilsp = {
		default_config = {
			cmd = {'golangci-lint-langserver'},
			root_dir = lspconfig.util.root_pattern('.git', 'go.mod'),
			init_options = {
					command = { "golangci-lint", "run", "--output.json.path", "stdout", "--show-stats=false", "--issues-exit-code=1" };
		};
	}
end
lspconfig.golangci_lint_ls.setup {
	filetypes = {'go','gomod'}
}

Support for golangci-lint-langserver is built-in to lsp-mode since late 2023. When the golangci-lint-langserver executable is found, it is automatically started for Go buffers as an add-on server along with the gopls language server.

You can use .golangci.yaml in the project root directory to enable other linters

[[language]]
name = "go"
auto-format = true
language-servers = [ "gopls", "golangci-lint-lsp" ]
[language-server.golangci-lint-lsp]
command = "golangci-lint-langserver"
[language-server.golangci-lint-lsp.config]
command = ["golangci-lint", "run", "--output.json.path", "stdout", "--show-stats=false", "--issues-exit-code=1"]

• For golangci-lint v2+: Use --output.json.path stdout --show-stats=false parameters
• For golangci-lint v1: Use --out-format json parameter
