While you can not buy products where no part is made in China, you very often have a choice where to allocate profits from your purchase.
For example, if you buy Huawei phones, then most of the money goes to China. If you buy from a non-Chinese company, the extend is less.
As to the people who just instinctively respond with whataboutism: China is a dictatorship that not only commits genocide against Muslims in Xingjiang, they are also overtly hostile to anyone, especially any country, not directly supporting their view of censorship and social control.
How you personally deal with the US and US products, is your choice. In the same way.
But let me say one thing: As many faults as the US has, it has nothing on China when it comes to the suppression of freedom of speech.
For example, everyone and their mom makes fun of Trump, and Americans. Or Germans, or British. Or whatever.
But make fun of China or the CCP in any way, and a wave of threats, both political and personal, descent upon you - up to the highest level. Ask that Swedish TV show... And you better never set foot into China after that.
Anyone who has the slightest idea about Chinese face culture, and its political environment, know that the two countries are simply not comparable in that regard. And whatever wrongs the US has, it has them for completely different reasons.
