I don't know what autocomplete you're using but mine often suggests outright invalid words given the context. I work around this by simply not accepting them
The high failure rate of LLM-based autocompletes has had me avoid those kind of features altogether as they waste my time and break my focus to double-check someone else's work. I was efficient before they were forced into every facet of our lives three years ago, and I'll be just as efficient now.
Personally, I configure autocomplete so that LSP completions rank higher than LLM completions. I like it because it starts with known/accurate completions and then gracefully degrades to hallucinations.
