bug(llm): LLM attack surface detector does not work on selected ollama LLM

[psyray]

Current Behavior

When using an ollama LLM to use attack surface detector, the LLM is hardcoded to llama2-uncensored.
It's impossible to use the selected one, and it only works when llama2-uncensored is present in the ollama container
If not, 500 error

Expected Behavior

Selected ollama model should be used

Steps To Reproduce

1. Download an ollama LLM other than llama2-uncensored and select it
2. Add target and scan it
3. Choose a subdomain, and click Attack surface detector
