With plain AutoCAD:

To extend and trim two lines to each other with one action, you can use ROUND with a radius of 0. (No arc will be generated)

I just don't know any method to do this with thousands of lines at the same time.

(Maybe with LISP, but this could be dependant on the selection order, if it will mess up the drawing, or not...i guess)

...And if you have AutoCAD Mechanical, you can use AMJOIN.

You can use the extend command to extend and trim multiple lines in one step.

Give the extend command and then select the line you want to extend the lines to and press Enter.

Now use the window cross option (click right-to-left to define the cross window) making sure the window covers the ends of the lines you want to extend.
