That must be the ESLint error. You can still useconsole.log()or sayalert()statements for any debugging purposes (I can confirm this as I have used this in couple of my LWCs).

You are most likely encountering ESLint errors in VS Code.
As an example below is how my code looks like with those warnings. However I am still able to save the component and utilize alert or console.log statements specifically for debugging purposes.
You can also choose to suppress those warnings by right clicking on those warnings
OR
By editing the .eslintrc.json available in your project by adding the below rules:
"rules": {
"no-console": "off",
"no-alert": "off"
}
Console showing errors
Option to disable the rules by right clicking on the alert
