Recently I heard the sentence:
強い、より命令ぽくってその人がこうもらえると思ってるものを返してほしい
when the teacher was trying to explain difference between "要望" and "要求".
I am wondering if "ぽくって" is the informal "テ形" of "っぽい" because it looks like "っぽくて".

It is exactly as you stated.
Using 「Word + っぽい」 over 「Word + ぽい」 is actually a "recent" phonetic trend in the history of the language. The trend is only about 100-plus years old.
If you read novels from Meiji Era (1868 - 1912), you will notice the coexistence of both forms.
「~~くって」 is the colloquial form of 「~~くて」 and it is very common in our spoken language. It is, of course, the te-form of an i-adjective.
e.g. 「このリンゴはあまく(っ)ておいしい。」("This apple is sweet and yummy.")
It can, however, be kind of difficult (and even stressful) to utter 「命令{めいれい}っぽくって」 with two small っ sounds in such a short phrase because, as in any language, we tend to speak fast in our informal conversations.
Thus, uttering either 「命令ぽくって」or 「命令っぽくて」 using only one small っ would be much easier.
I think this is why the person in question said 「命令ぽくって」 (almost) instinctively as a native speaker.
