This part constitutes the main part of your essay
If the question does not ask our opinion explicitly, would my mark be reduced if I use the phrases like”I believe, I think” couple of times in the essay (spesifically in introduction and conclusion) ? While writing introduction after paraphrasing the question I wrote ” In this essay, I will outline the reasons etc…) and I am worried now it will prevent me from getting band 8.

Part of your IELTS preparation is developing ideas for topics. This is something you do for yourself. You can google ideas and visit debate websites as well as read model essays online to use their ideas (not their sentences, just the ideas). See this page about writing an introduction:
I have written a task2 essay recently, using the topic of TEST 1 in BOOK 9.
The topic is “Some experts believe that it is better for children to begin learning a foreign language at primary school rather than secondary school. Do the advantages of this outweigh the disadvantages?”
I paraphrased the statement and gave my own opinion in the introduction. But which confuses me is that the official model answer prepared by an examiner doesn’t have any statement about giving an opinion and doesn’t mention which one is more advantageous. So I wonder whether it’s necessary to give my own opinion in this type of questions.
