Does Jujutsu have many Aikido like techniques?

you are partially correct. What I must point out is that the term Jujutsu is a generic word describing many of the styles that were used during the Samurai era. And Aikido does have many techniques like those found in the various styles of Jujutsu. To further describe Aikido it does in fact have some striking. But many people have assumed it does not simply because of the image that has been given that Aikido is only defensive, and only defends. That said I must also point out that while we as martial artists are not supposed to start a fight, if it can't be avoided, then we are acting defensive by attacking first. What many people seem to misunderstand is this.... All martial arts have both offensive and defensive techniques. The confusion comes from the morals drilled into everyone, especially arts like Aikido.

Aikido is a direct descendant of several Samurai jujitsu systems that remained in Japan at the end of the 19th Century. Most of what you see in modern Aikido comes from early Japanese Jujitsu, not the other way around.

Most of the similarities that modern Japanese jujitsu has with Aikido are not the result of jujitsu practitioners borrowing from Aikido, but they are the result of Jujitsu and Aikido having the same parent styles.

Yes. Quite a few of the Aikido joint locks. Ikkyo, nikkyo, sankyo, and kotegaeshi, can all be found (i.e., have been kept from:) in Jujitsu.
