Welcome to the Forum.  It is hard for me to imagine a circumstance in which a reputable person would sell a used, contaminated dildo.  Even if they did however HIV and other STIs are not transmitted on inanimate objects, particularly if the object has been washed before it is used.  Thus in answer to your questions:

1.  No

2.  The internet is, as it does so often, misleading you.  No STI viruses, including HIV would survive on an inanimate object for two weeks.

3.  There is no need for testing of any sort in relationship to use of the dildo you have described.

I hope that these comments are helpful to you. Please don't worry and please stay off of the internet- much of what is found there is incorrect, taken out of context, or just plain wrong.  EWH
