// Please note that there are multiple options where LLM providers might stream sources:
//
// - As part of the delta content while streaming. That would be part of this class.
// - By using a dedicated stream event and data structure. That would be another class implementing IResponseStreamLine.
//
// Right now, OpenAI uses the latter approach, so we don't have any sources here. And
// because no other provider does it yet, we don't have any implementation here either.
//
// One example where sources are part of the delta content is the Perplexity provider.
